Kathleen Schlesinger, 1911 Encyclopædia Britannica, Volume 24… (1911)
“ In Germany these structural differences have given rise to a classification of brass wind instruments as whole or half instruments (Ganze or Halbe) , [1] according to whether the whole or only the half of the length of tubing is of practical use. The members of the saxhorn family are the small saxhorn in E♭, the soprano in B♭, the alto in E♭, the tenor in B♭, the bass in B♭ (an octave lower) , the low bass in E♭, the contrabass in B♭, three octaves below the soprano. All the saxhorns are treated as transposing instruments. ”
