Improvising Duos - Audio only

This dataset comprises the audio recordings created as part of the Improvising Duos project. A small portion of the complete audio recordings were used to create the stimuli for the perceptual study reported in Moran, Hadley, Bader and Keller (2015), Perception of 'Back-Channeling' Nonverbal Feedback in Musical Duo Improvisation', PLoS ONE 10(6), where the data collection procedure is described. The dataset presented here comprises two parts: six pairs of improvising musicians recorded a series of short performances of the jazz standard, Autumn Leaves; six pairs of musicians recorded a series of short free improvisations. All 12 duos - across both styles - were instructed to play to a formula which encouraged short solo episodes (entirely unaccompanied by their partner). The audio recordings for each duo include two to four tracks. Separate audio tracks were recorded for each musician, using two Audio Technica AT 2035 condenser microphones; in addition, digital instruments were recorded with a direct line in. The audio files for each of the 12 duos consist of a number of short performances; these individual 'takes' are cross-referenced in the accompanying text through start and end times (s).
