När klarinetten låter dåligt - en identifikationsstudie
Opponent: Birgitta Burger
In wind instruments, tone quality is an important sound feature which
strongly depends on the player. The subject for this study was to examine
perceptually when a clarinet tone sounds bad, how it sounds, and what this
Analysis of previous clarinet recordings, interviews and a listening test
gave insight on what the most common mistakes and their causes are.
Results show that professional clarinetists and teachers quite reliably
can identify the possible cause of a bad tone. Also, a number of ordinary
methods for avoiding typical playing errors were acquired.
Spectrum characteristics of clarinet tones were analyzed acoustically. It
was not always feasible to find common characteristics for a certain error
category, but some tendencies and cues that distinguish categories of bad
tones have been found and are discussed. An algorithm for the
differentiation of these tones was written for automatically being able to
find any bad tone in a recording. This is an important issue for computer
aided learning, especially with instrument beginners as they are likely to
make such basic errors.
