- 요약To produce a characteristic tone, stringed instrumentalists must develop a variety of right hand or bowing techniques (e.g., bow hold and bowing motion). Pedagogues, acoustics researchers, and music researchers have highlighted the importance of weight, speed, and placement on stringed instruments' waveform and perceived tone. As a secondary variable, tilt may produce a subtle-yet important-variation in tone quality. Examining the acoustical and perceptual effects of bow tilt may offer educators evidence-based practices that can inform teaching and student learning outcomes. The purpose of this study was to examine the effects of bow tilt on acoustical and perceptual measures of timbre in violin and cello performances. Participants (N = 41) were violinists and cellists who were recruited from a large southern university. Participants performed a short melodic excerpt twice using flat hair and tilted hair in a counterbalanced order. I asked the performers to maintain consistent bow placement and speed throughout the performance. I analyzed seven acoustical elements (i.e., intensity, spectral centroid, harmonic to noise ratio, spectral irregularity, long-term average spectrum [LTAS], log attack time, and attack slope) during four target notes of the same notated pitch. I analyzed each instrument's acoustical data separately using a mixed factorial design with two within-subject factors (i.e., bow tilt and note) and one between-subject factor (i.e., order). Additionally, participants rated their tone using semantic differential scales and described their tone in free response questions. I used a mixed factorial design with one within-subject factor (i.e., bow tilt) and two between-subject factors (i.e., order and instrument) to examine the perceptual data. I used an iterative deductive content analysis approach to code and describe the performers' descriptions of tone performed with flat and tilted hair.Acoustical results indicated a significant main effect of bow for the violinists' and cellists' measure of intensity and LTAS. For both instruments, the flat bow condition produced higher intensity and LTAS measures compared to the tilted bow. A main effect of note was found for both violinists' and cellists' measures of spectral irregularity, harmonic to noise ratio, LTAS, and attack slope, indicating that these acoustical measures varied according to melodic placement. Additionally, results indicated a main effect of note on the cellists' log attack time. I found a significant Bow x Note interaction for the violinists' spectral centroid and log attack time measures, indicating that the effects of bow tilt were further influenced by the location of the note. Violinists' intensity differed significantly between flat and tilted bow conditions, but those effects were not independent of order, as evidenced by the significant Note x Order interaction. No other significant acoustical results were found. A main effect of bow was found for the perceptual measures of loudness, fullness, resonance, and overall tone, with the flat bow condition being rated higher than the tilted bow. However, a significant main effect of order was found for the overall tone measure. Additionally, a main effect of bow was found for the participants' rating of attack quality where the tilted bow hair's attack quality was rated higher-i.e., scratchier-than the flat hair condition. I found a significant two-way interaction of instrument and order for participants' ratings of fullness and resonance, signifying that participants' ratings varied according to both instrument and order. Results indicated a significant two-way interaction of bow and order for participants' ratings of brightness.Participants identified which performance they preferred, and results indicated a small but non-significant preference for the flat hair performance. Participants were also asked to identify which bow condition (i.e., flat or tilted) matched their typical performance. Results indicated that more participants used flat hair as their default; however, there were no significant differences. When describing the tone quality of the flat and tilted hair performances, participants' responses aligned with the following coding categories: (a) sensory codes, (b) mass codes, (c) playing perception codes, and (d) tone as a musical element. In conclusion, the amount of bow hair touching the string resulted in acoustical changes in tone both for violinists and cellists, and those changes were perceptible to participants. These findings provide empirical data that can inform string performers and educators about specific strategies to modify their tone. Additional implications and suggestions for future research are discussed.
