Clarinetas em Si Bemol e em Lá: diferenças acústicas e interpretativas

Abstract

The Bb and A clarinet have been used by professional clarinetists inany of their orchestral or chamber music activities. Both instruments can be played with the same mouthpiece and reed, both are chromatic instruments and have the same range, except by the unique A clarinet lowest semitone. This work have investigated the real timber differences between the two instruments from a comparative study based on perception experiments. An timbre spectrum analysis of notes from both instruments was also performed. The tests showed us that it was impossible to detect surely timber differences from the A clarinet to the Bb one and the sound analysis have demonstrated a big timber similarity between both instruments.
