Query: Decision-Based Transcription of Jazz Guitar Solos Using a Harmonic
  Bident Analysis Filter Bank and Spectral Distribution Weighting   Jazz guitar solos are improvised melody lines played on one instrument on top
of a chordal accompaniment (comping). As the improvisation happens
spontaneously, a reference score is non-existent, only a lead sheet. There are
situations, however, when one would like to have the original melody lines in
the form of notated music, see the Real Book. The motivation is either for the
purpose of practice and imitation or for musical analysis. In this work, an
automatic transcriber for jazz guitar solos is developed. It resorts to a very
intuitive representation of tonal music signals: the pitchgram. No
instrument-specific modeling is involved, so the transcriber should be
applicable to other pitched instruments as well. Neither is there the need to
learn any note profiles prior to or during the transcription. Essentially, the
proposed transcriber is a decision tree, thus a classifier, with a depth of 3.
It has a (very) low computational complexity and can be run on-line. The
decision rules can be refined or extended with no or little musical education.
The transcriber's performance is evaluated on a set of ten jazz solo excerpts
and compared with a state-of-the-art transcription system for the guitar plus
PYIN. We achieve an improvement of 34% w.r.t. the reference system and 19%
w.r.t. PYIN in terms of the F-measure. Another measure of accuracy, the error
score, attests that the number of erroneous pitch detections is reduced by more
than 50% w.r.t. the reference system and by 45% w.r.t. PYIN.
