Ambos os instrumentos podem ser executados com a mesma boquilha e palheta, s?o crom?ticos e compreendem o mesmo registro, com a diferen?a ?nica do semitom mais grave da clarineta em L?. Este trabalho investigou as reais diferen?as t?mbricas entre os dois instrumentos a partir de um estudo comparativo baseados em experimentos de percep??o. Foi tamb?m feita uma an?lise dos espectros de freq??ncia de notas de ambos os instrumentos. Observou-se que os participantes dos experimentos foram incapazes de identificar com seguran?a diferen?as t?mbricas entre as clarinetas em L? e Si bemol e as an?lises demonstraram grande similaridades entre os timbres destes instrumentos.ABSTRACT: The Bb and A clarinet have been used by professional clarinetists in any 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
