Abstract |
The aim of this work is to acquire, study and model the blowing pressure profiles during the real performance of the recorder. Among all the possible performer gestures that take place in real performance, i.e. blowing pressure, finngering or embouchure, the blowing pressure has been selected as the most representative and measurable. A direct acquisition system was developed with pressure sensors. Two prototypes were designed and the second one was improved by a recorder luthier in order to acquire more accurate and reliable measurements. After that, a professional recorder player performed a recording script that was designed in order to cover a representative subset of the different performance techniques. The recordings of the sound and the gesture shape the multimodal database. The analysis of the blowing pressure profiles was done looking carefully at four analysis dimensions: pitch, articulation, dynamics and note duration. A set of features was defined and studied in order to characterize temporally the profiles. An initial temporal model was developed for certain features. |
