In the past, musical instruments were developed overlong periods of time by skilled craftsmen. Today,most instruments are mass-produced. Design of musical instruments as mass-produced products requires using strategies which makeiteasier to identify customer needs and develop exact specifications. To develop useful specifications it is necessary to convert general descriptions into something which can be commonly understood and also be interpretable in terms of acoustic metrics. In this study,m ethods for analysis and specification of steady state parts of alto saxophone sounds were developed. Saxophonists' use of verbal descriptions of saxophone sounds wasi nvestigated. Sound stimuli were binaurally recorded. Judgements upon perceivedq ualities were made by saxophonists and non-saxophonists using the method of verbal attribute magnitude estimation. Perceptual dimensions were identified using principal component analysis of listening test data. Three prominent dimensions were found and described using the verbal attributes: 1) warm/soft, 2) back vowel analogues and 3) sharp/rough. The perceptual dimensions were modelled as linear functions of acoustic metrics. The results were validated through listening tests with news ubjects and news timuli. Based on the findings, the method wass een as an approach which can enhance the musical instrument design process.
