Audio files are captured using the built in microphone in our laptop. It acts as a reference for the acquired gestures in the MIDI file. We use 10 MIDI channels (one channel per sensor) and the capacitance is stored as Pitch Bend message for a higher resolution. Messages are not synchronized showing a sampling rate between 20 and 30[Hz].

Experiments SMC 2010

Recordings for the paper "Analyzing Left Hand Fingering in Guitar Playing", published at SMC 2010 (see Publications page).

Table 1 show the possible combinations for the most common finger position over 4 frets. We use the following nomenclature: 4 digits refer to 4 successive frets. Each digit corresponds to the number of fingers pressing at the same fret. These positions can be played in different hand positions and in different strings. 6 refers to  bar activation, 1 refers to 1 finger activation at any string,  2 refers to 2 finger activation at the same fret at any strings, and  3 refers to 3 finger activation at the same fret at any strings. The highlighted combinations represent the recorded cases.

Table 2 shows a detailed list of all the recorded positions, specifying the played strings. Each recording includes the hand position moving from fret 1 to 7. The s1..s6 stands for the played string. Each string specification follows an ascending order from finger 1 to 4. For instance, 1110s5s4s6 stands for 1 finger over the 1st, 2nd and 3rd consecutive frets, with fingers pressing the 5th, 4th and 6th string, respectively.

MP3 files are recorded as an audio reference (not in studio) and the information in MID files is saved as Pitch-Bend information (higher resolution) for channels 1..10, according to the each fret (fret 1 is near the nut, and fret 10 is near the hole).
