While results of the audio-visual condition versus audio-only condition indicate no significant difference, written evaluation analysis provided other interesting information and raised other questions. Does the visual element possibly increase subjects' understanding, interest, curiosity, liking or valuing? This paper examines the effect of modes of presentation on the evaluation of marching band by musicians and nonmusicians. For this study, 135 musicians and 78 nonmusicians were randomly assigned to three experimental groups: audio-only, visual-only, and combined audio-visual. The stimuli used for the experimental conditions were two contrasting marching bands commercially recorded at a "live" marching band competition, one performing The Inferno, by Robert Smith (One minute, 58 seconds), and the other performing Gavorkna Fanfare, by Jack Stamp (One minute, 32 seconds). Subject demographic data were collected by means of a questionnaire. Subjects completed a written evaluation assigning an overall numerical-preference rating indicated no significant between groups or among treatments. There was a significant difference between ratings for Example One and those for Example Two. For the free response questions, on the whole, subjects made more nonmusical comments and musical comments. The findings of this study indicate that musicians made more musical comments than nonmusicians. Results indicated a difference among viewing conditions with audio-only receiving the highest percentage of musical comments and visual-only receiving the lowest. Example Two received higher percentage of musical comments than did Example One. Introduction Marching band has enjoyed a high profile in American music education for a long time. Fans of all ages and occupations support it. During half-time shows, parades, and other celebrations, marching bands draw crowds. Not only do marching bands have a visual impact on audiences, but they also have an audio impact. It is not clear whether it is the musical (or audio) aspect, the visual aspect or a combination of both that captures the attention of so many people. Research into the specific elements of marching bands has not received a great deal of emphasis. However, music educators have conducted studies concerning the evaluation of auditory versus visual aspects of teaching and ensemble performances. Johnson (1991) found that musicians rate marching bands higher when they are presented with audio-visual versions rather than audio-only versions of the performances. Moreover, musicians focus on different musical elements than do nonmusicians (Madsen and Geringer, 1990). Flowers (1983, 1984) discovered that nonmusicians most often use nonmusical, or extra musical phrases when asked to describe music. Furthermore, musicians almost never attempt to describe a musical event unless they have a musical term for it. Subjects who received music only tended to respond with musical answers, while those who received music and video tended to respond more frequently with visual answers (Cassidy & Geringer, in press; Killian, 1995). Geringer, Cassidy, and Byo (1996) found that subjects in a music-plus-video group received higher scores on both cognitive and affective measures than those in a music-only group. Previous studies that utilized videotaped musical performances were concerned with the evaluation of musical performance and music teaching, McClaren (1988) found that college music majors preferred videotaped to audiotaped marimba performances. Cassidy and Sims (1991) concluded that a videotaped performance of handicapped children's choir had a positive effect on performance evaluations by practicing music teachers. Yarbrough and Hendel (1993) found that videotaped and scripted presentations of sequential patterns of instruction resulted in higher elementary and high school student evaluations of teaching than did audio-only and video-only presentations. In a study of violin vibrato, Gillespie (1994) found that videotaped performances of inexperienced string players' vibrato technique were rated higher than performances that were only audiotaped. Fredrickson (1994) designed a study to determine the effect of losing visual and/or aural stimuli on band members' ability to perform with an ensemble accurately. While the combination of aural and visual stimuli received the highest ratings, visual-only and aural-only group ratings were almost were almost identical. However, other studies using video technology as a treatment condition have yielded conflicting results. Neither Brown (1976) nor Blackburn (1986) found that videotaped music lessons affected music-listening. However, Forsythe and Kelly (1989), found that videotaped visual cues paired with audio music phrases enhance students' musical discriminations. In the study most closely related to this one, Johnson (1991) compared the evaluation of auditory versus auditory and visual aspect of musical performance in his study of marching band adjudication. He found that ratings of two different performances by college music majors were significantly higher in the audio-visual condition than in the audio-only presentation. The purpose of the present study was to extend Johnson's research in two ways: (1) to expand the treatment conditions from two (auditory vs. auditory and visual) to three (auditory vs. visual only vs. auditory and visual); and (2) to include not only musicians as evaluators but also nonmusicians. In addition, the present investigation examined the amount of musical information subjects described when presented with marching band performances. The research questions were: Will there be a significant difference in preference and the amount of musical information described under audio-only, visual-only, or audio-visual conditions? Will there be a significant difference in preference and the amount of musical information described by musicians and nonmusicians? Will there be a significant difference in preference and the amount of musical information described attributed to different musical and marching styles of the selections? Procedure Subjects were undergraduate music (n=135) and non-music (n=78) majors at a major southern university. Non-music subjects were defined as those students having no more than 3 years of formal music training. Musicians and nonmusicians were randomly assigned, respectively, to one of the three treatment groups: audio-only, visual-only, and audio-visual. Half of the subjects in each group heard Band 1 followed by Band 2; the other half heard Band 2 followed by Band 1. Groups 1 (n=41 musicians) and 4 (n=24 nonmusicians) listened to the audio-only portion of the stimulus tape. Groups 2 (n=51 musicians) and 5 (n=28 nonmusicians) experienced the visual-only portion of the stimulus tape. Groups 3 (n=43 musicians) and 6 (n=26 nonmusicians) experienced the combined audio-visual condition of the stimulus. The stimulus was selected after a thorough review of videos of live marching band performances. Two experimental bands were judged by a panel of experienced band directors to be equal in marching and playing proficiency. In addition, the music played by the two bands was judged by these experienced band directors to be unfamiliar to most subjects. One important criterion was that there should be contrasting musical and marching styles between the two bands. Further selection criteria included quality and length of the performance as well as placement in the marching band show (both excerpts were show openers). Examples averaged 1 minute and 45 seconds in length, with a range of 1:32 - 1:58. Total presentation time for both examples including twenty seconds of silence between them, was 3 minutes and 50 seconds. A list of the two bands, the two musical excerpts, and the timing for each excerpt is presented in Table 2. Table 2 Videotaped Marching Band Examples Example Musical Excerpt Duration 1 The Inferno by Robert Smith 1:58 2 Gavorkna Fanfare by Jack Stamp 1:32 The taped excerpts were recorded from a commercially produced recording, Bands of America, that shows the semi-finals of the Grand National Championship, performed and recorded live in Indianapolis, Indiana, November 7-9, 1996. The Inferno (Example One) is the first movement of Robert Smith's work, The Divine Comedy. This work was selected because of its strong programmatic portrayal of Dante's The Divine Comedy in both musical and marching aspects. It is contemporary in nature and includes furious woodwind ostinatos, huge blocks of sound, tremendous percussion, and the imagery of Hell's Inferno. The show began with a 16 measure count off by the drum major with some minor percussion accompaniment in the background. It moved on to a saxophone solo with another actor acting out a scene. The music suddenly changed into a loud and bombastic nature with girls dressed in bright red and yellow jumping on trampolines. The musicians were dressed in black cloaks with white painted faces. The compositional and marching style of Smith's The Inferno was a contrast to Example Two, Jack Stamp's Gavorkna Fanfare. This fanfare is an exciting piece to open the marching band show and it also depicted a more traditional marching style. This vigorous fanfare for full wind band utilized brisk articulations and a large percussion section including bells, chimes and vibes. The show began with the crowd cheering in the background. The camera was focusing on the two female conductors. Various parts of the show formations were shown throughout the music. The musicians were wearing school band uniforms and several sections of the band were featured specifically. This included the chimes, bells and drumline segments. The two examples were dubbed onto two Sony Grade VHS Tapes. The order of presentation of the two examples was counterbalanced, so that approximately half of the subjects in each group were presented with Example 1 followed by Example 2, and the other half of the subjects were presented Example 2 followed by Example 1. Twenty seconds of clear screen and/or silence were recorded between each example. Equipment used for this process were two Panasonic Hi-Fi Video Cassette Player, AG-2550P. Data were collected during regular class meetings in regular classrooms. Seating was arranged that each student was able to view the television monitor easily. Subjects then completed a short demographic questionnaire. A two-page response sheet was provided which allowed adequate room to write comments following each example. The researcher reviewed the questions with the subjects before the examples were presented. They were told to pay full attention to the performance and to write their comments after the performance. After each example, subjects were given ample time to answer the questions on the response sheet. An opportunity was given for questions before the tape began. No interruptions or disturbances were allowed during the experiment. Audio presentations were from the corresponding video soundtrack. The television monitor was covered for the audio-only treatment condition to ensure that the quality of sound remained consistent among all treatment groups. For visual-only treatment, the volume control of the television monitor was turned to zero. The equipment used for administrating the treatments was a Panasonic 20" Stereo TV/Hi-Fi VCR combination. Upon the completion of experimental treatments, preference ratings were tabulated and written responses were categorized by the researcher as musical or nonmusicial. Categorization accuracy was established by a reliability observer who independently categorized 25% of the responses. The percentage of agreement between the two observers was .94, using the formula, agreements divided by agreements + disagreements. Results The study was designed to investigate the effect of aural, visual, and aural/visual conditions on the evaluation of marching bands by musicians and nonmusicians at a major southern university. Data were gathered from individual responses to two marching band examples under the three experimental conditions through a written evaluation assigning an overall liking and citing three things that were liked most, liked least, and held attention during the performance. Demographic data were collected from each subject. Question One: Ranked Preference Responses Question One was, "Did you like the performance?" Subjects were asked to respond from 1(No) to 5(Very Much). Responses were analyzed using a two factor ANOVA comparing groups (musicians vs. nonmusicians) and treatments (audio-only vs. video-only vs. audio-visual) with repeated measures on Examples One and Two. Results showed no significant differences in preferences between groups or among treatments (see Table 3). There was a significant difference between preferences for Example One and Example Two. Mean preferences for Example One were greater (M=3.53) than Example Two (M=3.29). No other significant differences were found.

Musical comments were defined as "Any comments which refer to musical sounds, instruments or events; any comments which specifically mention sounds, instruments or events; any comments which specifically mention music" (Killian, 1995). Nonmusicial comments were defined as any statements referring to anything except music. The written responses to each excerpt were analyzed by scoring one point for each musical comment, and one point for each nonmusical comment. An overview of the data revealed that a total of 3, 655 comments were made by 213 subjects (ranging from a low of 7 comments on the two examples to a high of 27 comments). Responses to Question Two totaled 1, 328; responses to Question Three totaled 1,080; and responses to Question Four totaled 1, 247. It was found that subjects wrote the most comments on Question Two (M = 2.08), followed by Question Four (M = 1.95) and they wrote the least comments on Question Three (M = 1.69). Examination of the overall comments scored indicated that musicians were more verbal (M = 8.81) than nonmusicians (M = 8.19). However, the differences were minimal. In the different treatment conditions, subjects made the most comments (M = 8.71) under the audio-only condition, followed by the visual-only condition (M = 8.53), and the least comments under the audio-visual condition, (M=8.48). Here again, the differences were minimal. After musical and nonmusical comments were counted, frequencies were converted into percentages of musical and nonmusical comments by examples (one and two), group (musicians and nonmusicians) and treatments (audio-only, visual-only, and audio-visual). Questions Two and Three: Liked Most vs. Liked Least Question Two was, "List three things that you like most about the performance." Question Three was, "List three things that you like least about the performance." First, I examined musical comments for these two questions. Combining responses from Questions Two and Three, it was found that overall musicians (44.50%) made more musical comments than nonmusicians (42.18%) (see Table 4). However, there were several instances where nonmusicians made more musical comments than musicians. There were under Question Two, Example Two video-only; Question Three, Example One audio-only; and Question Three, Example One and Example Two of the visual-only condition. Results indicated some differences in the percentage of musical comments among viewing conditions with audio-only (72.22%) receiving the highest percentage of musical comments, followed by audio-visual (33.47%), and visual-only (24.29%) receiving the lowest. Finally, Example Two (45.83%) received more musical comments overall than Example One (40.91%). There were four instances where Example One received more musical comments than Example Two. These were musicians' responses to Question Two in the audio-only and visual-only conditions as well as nonmusicians' responses to Question Three in the audio-only and visual-only conditions. Next, I examined the nonmusical comments. Combing the responses from Questions Two and Three, it was found that nonmusicians (57.82%) made more nonmusical comments than musicians (55.4%) (see Table 5). However, there were several examples in which musicians made more nonmusicial comments than nonmusicians. There were for: Question Three, Example One, audio-only; Question Two, Example Two, visual-only; and Question Three, Example One and Two, visual-only condition. On the whole, all subjects wrote more nonmusicial comments for Question Two (57.07%) compared to Question Two (56.20%). Results indicated a difference among viewing conditions with visual-only (75.51%) receiving the highest nonmusical comments, followed by the audio-visual (66.53%), and audio-only (27.78%) receiving the least. Table 5 Mean percentages of Nonmusical Comments: Questions (Liked Most vs. Liked Least) by Examples, Groups (Musicians vs. Nonmusicians), and Treatment Conditions (Audio-only vs. Visual-only vs. Audio-visual). Questions Two Liked Most Question Three Liked Least Treatment Group Example 1 Example 2 Example 1 Example 2 Musicians 11.38 12.40 42.64 40.45 Audio Nonmusicians 26.39 13.32 32.99 43.30 Musicians 87.65 91.14 67.09 63.63 Visual Nonmusicians 98.81 91.01 44.35 60.42 Musicians 68.95 50.39 71.55 57.95 Audio- visual Nonmusicians 73.91 59.49 83.33 66.67 Finally, Example One (59.09%) received more nonmusical comments than Example Two (54.17%). There were four instances where Example Two received more nonmusical comments than Example One. They were for: musicians under the audio-only and visual-only condition for Question Two; and nonmusicians under the audio-only and visual-only conditions for Question Three. Question Four: Held Attention Question Four was "List three things that held your attention in this performance." First, I examined the musical comments. For Question Four, it was found that musicians (41.76%) made more musical comments than nonmusicians (38.70%) (see Table 6). However, for Example Two, audio-only condition, nonmusicians made more musical comments than musicians. Table 6.

Finally, Example Two (44.16%) received more musical comments than did Example One (36.29%). Next, I examined nonmusical comments. For Question Four, it was found that nonmusicians (61.30%) made more nonmusical comments than musicians (58.24%) (see Table 7). However, under Example Two, audio-only, musicians made more nonmusical comments than nonmusicians. Results indicated a difference between viewing conditions with visual-only (87.92%) receiving the most nonmusical comments percentage, followed by the audio-visual (71.94%), and audio-only (10.47%) receiving the least. Finally, Example One (63.29%) received more nonmusical comments than did Example Two (55.84%). Table 7.

Discussion Results of this study showed in the ranked preferences, there was no significant differences between musicians and nonmusicians or among treatment conditions; but, there was a significant difference preference for between Example One and Example Two; with a greater preference for Example One. This finding is similar to that of Geringer, Cassidy, Byo (1996, 1997) where the animated example scored higher than the abstract example. For the free preference responses from Questions Two, Three, and Four, musicians wrote more musical comments than nonmusicians; the audio-only condition received the most musical comments, followed by audio-visual condition, with the visual-only receiving the least; Example Two received more musical comments than Example One. It should be remembered that overall, subjects wrote more nonmusical than musical comments. It is interesting to note that Smith's Inferno (Example One) is more popular than Stamp's Gavorkna Fanfare (Example Two). Reasons for this were noted: visual effects, the originality and creativity of the performance, colorful costumes, incorporation of drama, and different types of props. On the other hand, subjects wrote more musical comments on Stamp's Gavorkna Fanfare. The chimes and bells as well as the percussion segments in the work caught the attention of most subjects in all the three different conditions. Subjects in the visual-only and audio-visual conditions were not distracted by the costumes, props, and drama. Something worth taking note of is that the music vocabulary that musicians and nonmusicians used was different. Musicians used a wider range of musical descriptive terms than nonmusicians. Nonmusicians tended to mention "drums," "bells," and "tempo." Musicians, on the other hand, used more specific and precise music terms like "brass," "percussion," "quads," "intonation," and "drumline." Moreover, most of the subjects in this study made references to the tempo, timbre, and dynamics which supports the Flowers (1987) and Robinson (1987) studies. In addition, the use of marching band terminology was found among musicians. Descriptions like "phasing problem," "intervals," "forms hits together," "marching style rolling feet," and "spacing wasn't exact," were used. Moreover, words like "pit" and "drumline" were used by people who were more familiar with the marching band context. This could be due to the fact 48.15% of the musicians had more than three years of marching band experience. Under the audio-only condition, the written evaluation forms showed the greatest number of musical comments which is similar to the Killian (1995), Cassidy and Geringer (1996), Geringer, Cassidy and Byo (1996, 1997) findings. Moreover, this condition received the most responses contradicted the Burnsed and Etters (1997) where the audio-visual condition stimulated more responses. Written comments taken from the test concerning positive and negative aspects of the performance appeared to be similar between musicians and nonmusicians. Things most liked about Example One were "flute" and "drums." Characteristics most liked about Example Two included: "bells," "drums," "chimes," "tempo," "rhythm," and "upbeat." The least liked aspects of the performance reported by groups were: "the count-off," "the towel," "recording quality," and "no video." One subject commented that the "Drum major 16 count-off was distracting but necessary." One musician wondered, "Why they didn't use a radio?" for this exercise. A number of subjects expressed their frustration, but not as strongly, in the visual-only condition. If this activity had been listening to a compact disc recording or concert recording, they might have more readily accepted the performance. The fact that subjects recognized that it was a marching band made it more difficult to accept listening without watching the show. For the ranked preference responses, under the audio-visual condition, were not significantly different from those in the audio-only or video-only conditions. This finding was similar to those of earlier studies by Adams (1994), Brown (1976), Blackburn (1986), and Burnsed and Etters (1997). However, this result conflicts with the findings found by Fredrickson (1992), Cassidy and Sims (1991), Yarbrough and Hendel (1993), Gillespie (1994), and Johnson (1991) where the audio-visual condition was rated higher than the audio-only performance. It is interesting to note that proportion of nonmusical comments under the audio-visual condition was more than 50%. This conflicts with Killian's study (1995) where there were more musical comments in the audio-visual condition. The main reason could be that the marching band performance was more appealing and there are other variables involved. Not surprisingly, audio-visual subjects made more comments referring to visual information than the music-only listeners (Cassidy & Geringer, 1995; Geringer, Cassidy & Byo, 1996, 1997). Most visual-related comments had to do with the coordination of marching and music. For example, the costumes and props were mentioned quite frequently. One musician commented that, "What was the music? I didn't even listen because of all this. The costumes + props were distracting." Visual stimuli might possibly increase subjects overall attentive behavior. However, since some research suggests that high levels of simultaneous focus of attention do not exist (Madsen, 1987), it might be assumed that the presence of a visual stimulus might also "compete" for listeners' attention. Another musician made a negative comment about "the bell front tubas used rather than contras or sousaphones. This was not practical for anything but a competition." On the whole, most of the musicians did not recognize this as a marching band competition. It is interesting to note that visual-only condition is similar to Killian (1995). Watching a screen without sound and responding may be new for many subjects and might have created a level of uncertainty causing hesitation, confusion, or a general inability to make firm decisions concerning the task. The nonmusicians were more affected than musicians when they expressed displeasure for the task. Nonmusicians expressed more frustration than musicians at not being able to hear the music, and expressed a feeling of being "left out" of something. Musicians seemed to better understand and appreciate the nature of the task. Is watching a marching band video something different? Obviously watching and listening to marching band videos is not a "pure" music listening experience, nor is it the experience of a live band performance. High quality recording equipment may approximate the sound of live music to a degree of listener satisfaction, but the visual aspect of commercially produced concert videos is much different than that of live performances. For example, video productions provide viewers with close-ups, and views of performers not possible in a live performance. Network television uses unlimited camera shots and special effects to insure high entertainment value. In an attempt to hold viewers attention, the picture changes an average of every 3.5 seconds (Postman, 1986). Most concert video producers do not attempt to film the "music" but rather the intensity and commitment of the performers. "The rule of thumb ... is that the camera goes for the principal player as well as for the instruments that are most visually dramatic" (p. 37). Moreover, the question is whether a marching band should include the use of theatrics to enhance the performance and or remain as a traditional marching band. The marching band has evolved over the years from playing in a parade to providing an entertaining performance at halftime shows. Is the marching band heading towards a new direction in the 21st century? Can a video performance replace the "live" performance at the football stadium? This somewhat new listening experience might have strong implications for the music classroom and needs further investigation. The study of changes in music, music education, music society, and technology is a responsibility of the music research community. Not only is research needed to discover and test the innovations in music education, it is needed to improve existing aspects of music education that continue to have value. References Adams, B.L.
