Abstract [en]

Recent investigations on music performances have shown the relevance of singers’ body motion for pedagogical as well as performance purposes. However, little is known about how the perception of voice-matching or task complexity affects choristers’ body motion during ensemble singing. This study focussed on the body motion of choral singers who perform in duo along with a pre-recorded tune presented over a loudspeaker. Specifically, we examined the effects of the perception of voice-matching, operationalized in terms of sound spectral envelope, and task complexity on choristers’ body motion. Fifteen singers with advanced choral experience first manipulated the spectral components of a pre-recorded short tune composed for the study, by choosing the settings they felt most and least together with. Then, they performed the tune in unison (i.e., singing the same melody simultaneously) and in canon (i.e., singing the same melody but at a temporal delay) with the chosen filter settings. Motion data of the choristers’ upper body and audio of the repeated performances were collected and analyzed. Results show that the settings perceived as least together relate to extreme differences between the spectral components of the sound. The singers’ wrists and torso motion was more periodic, their upper body posture was more open, and their bodies were more distant from the music stand when singing in unison than in canon. These findings suggest that unison singing promotes an expressive-periodic motion of the upper body.

Abstract [en]

We examined the impact of the perception of singing togetherness,as indexed by the spectral envelope of the sound, and task complexity on choristers’ body motion, as they performed in duo with a pre-recorded tune presented over a loudspeaker. Fifteen experienced choral singers first manipulated the spectral filter settings of the tune in order to identify the recordings they felt most and not at all together with. Then, they sang the tune in unison and canon along with the recordings featuring the chosen filter settings. Audio and motion capture data of the musicians' upper bodies during repeated performances of the same tune were collected. Results demonstrate that wrist motion was more periodic, singer posture more open, and the overall quantity of body motion higher when singing in unison than in canon; singing togetherness did not impact body motion. The current findings suggest that some body movements may support choral performance, depending on the complexity of the task condition.

Abstract [en]

This volume presents the proceedings of the fifth Stockholm Music Acoustics Conference 2023 (SMAC), which took place on 14–15 June 2023 in Stockholm, Sweden. SMAC was premiered at KTH in 1983, and has been organized every tenth year since then. This conference is intended for academics, music performers and instructors interested in the field of Music Acoustics. It brings together experts from different disciplines, to exchange and share their recent works on many aspects of Music Acoustics, including instrument acoustics, singing voice acoustics, acoustics-based synthesis models, music performance, and music acoustics in teaching and pedagogy.

This time, our multidisciplinary conference was organized on a smaller scale than earlier, as a track within the 2023 Sound and Music Computing Conference, at KMH Royal College of Music and KTH Royal Institute of Technology. Our warm thanks are due to the SMC Network for hosting SMAC in the framework of SMC, as are many thanks to all presenters and co-authors for participating. We hope that you will enjoy learning of the new science presented here.

Abstract [en]

Objectives: To determine if in singing there is an effect of lung volume on the electroglottographic waveform, and if so, how it varies over the voice range. Study design: Eight trained female singers sang the tune “Frère Jacques” in 18 conditions: three phonetic contexts, three dynamic levels, and high or low lung volume. Conditions were randomized and replicated. Methods: The audio and EGG signals were recorded in synchrony with signals tracking respiration and vertical larynx position. The first 10 Fourier descriptors of every EGG cycle were computed. These spectral data were clustered statistically, and the clusters were mapped by color into a voice range profile display, thus visualizing the EGG waveform changes under the influence of fo and SPL. The rank correlations and effect sizes of the relationships between relative lung volume and several adduction-related EGG wave shape metrics were similarly rendered on a color scale, in voice range profile-style ʻvoice maps.ʼ Results: In most subjects, EGG waveforms varied considerably over the voice range. Within subjects, reproducibility was high, not only across the replications, but also across the phonetic contexts. The EGG waveforms were quite individual, as was the nature of the EGG shape variation across the range. EGG metrics were significantly correlated to changes in lung volume, in parts of the range of the song, and in most subjects. However, the effect sizes of the relative lung volume were generally much smaller than the effects of fo and SPL, and the relationships always varied, even changing polarity from one part of the range to another. Conclusions: Most subjects exhibited small, reproducible effects of the relative lung volume on the EGG waveform. Some hypothesized influences of tracheal pull were seen, mostly at the lowest SPLs. The effects were however highly variable, both across the moderately wide fo-SPL range and across subjects. Different singers may be applying different techniques and compensatory behaviors with changing lung volume. The outcomes emphasize the importance of making observations over a substantial part of the voice range, and not only of phonations sustained at a few fundamental frequencies and sound levels.
