The paper presents new approaches for analyzing the characteristics of intonation and pitch modulation of woodwind and brass solos in jazz recordings. To this end, we use score-informed analysis techniques for source separation and fundamental frequency tracking. After splitting the audio into a solo and a backing track, a reference tuning frequency is estimated from the backing track. Next, we compute the fundamental frequency contour for each tone in the solo and a set of features describing

Second, we analyze whether the intonation is artist-specific. Finally, we examine how the modulation frequency of vibrato tones depends on contextual parameters such as pitch, duration, and tempo as well as the performing artist.
