Citaat:
The saxophone was originally patented as two families, each of seven instruments. The "orchestral" family consisted of instruments in the keys of C and F, and the "band" family in Eb and Bb. Each family consisted of sopranino, soprano, alto, tenor, baritone, bass and contabass although some of these were never made (Sax also planned - but never made - a subcontra).
Of these the orchestral family are now rarely found, and of the band family only the soprano, alto, tenor and baritone are in common use (these form the typical saxophone sections of both military and big bands). The C-melody saxophone, a transposing instrument that is set in the key of C rather than Eb or Bb like the others, was popular in the 1920s and could read sheet music for guitar and piano in the correct key.
En voor zover ik weet werd de C melody ook gebruikt door profs, in de vroege big bands en dansorkesten. Ik kan me vergissen, maar volgens mij heeft Benny Golson hem ook af en toe gebruikt om qua geluid tussen alt en tenor te zitten.
