Resum
The dataset contains 23 multimodal recordings of string quartet performance. Acquired data includes the audio of each performance in separate tracks: up to two ambient tracks and individual tracks acquired through contact microphones. In addition each recording includes instrumental motion capture and a set of derived instrumental bowing descriptors for each musician. The recordings were made as part of the experiments on ensemble expressive performance.Descripció
The dataset contains five extracts from Beethoven’s Concerto N.4, Op. 18: (I) Allegro-Prestissimo movement, (P.1) Allegro ma non tanto movement (bars 54-78), (P.2) Allegro ma non tanto movement (bars 138-151), (P.3) Menuetto (bars 8-50), (P.4) Allegro-Prestissimo (bars 28-45). The piece (I) was recorded 3 times with increasing degrees of expressiveness: -Mechanical, -Normal interpreted, -Exaggerated. The pieces (P.1-P.4) were recorded 5 times each: -Ensemble performance, -Solo performance of Violin 1, -Solo performance of Violin 2, -Solo performance of Viola, -Solo performance of Cello, The musicians have given their explicit approval for this dataset to be made public. Audio Files: Each recording contains audio tracks in the "Ambient Audio" node: a cardioid microphone and a binaural microphone (this file is best experienced with headphones). In addition, each recording includes contact microphone recording of each musician in separate tracks. These audios are included in the "Pickup Audio" node. Score alignment: We place a score-performance alignment file per musician in the "Score Alignment" node of each datapack. The original score by Beethoven can be retrieved in various formats here. If downloaded, the score alignment file can be opened with a text editor and is written in human readable format. It contains, for each performed note a line like the following: onset-time-in-secs offset-time-in-secs note-pitch Polhemus MoCap Data: Bowing motion descriptors can be found in the "Instrument Gestures" node of each datapack. Within this node the bowing descriptors relative to each musicians are places on separate nodes. The raw Polhemus mocap data is found on the "Polhemus MoCap data" node and can be visualized by dragging such node to the first pane of in repovizz.
