Indirect Acquisition of Fingerings of harmonic Notes on the Flute

In this paper we present an approach for the realtime indirect acquisition of specific fingerings that produce harmonic notes on the flute. We analyse both temporal and spectral characteristics of the attack of harmonic notes which are being produced by specific control gestures involving fingering and potentially overblowing. We then show that it is possible to acquire this effect through signal analysis using a principal component analysis on the subharmonics of harmonic notes. An 8-fold cross-validation showed this approach to be successful for a single performer playing isolated notes.
