With a range from B♭3 to F#6, the saxophone has the warm sound of the clarinet combined with the nasal sound of the oboe.
Heckel began producing sopranino, soprano, alto, melody, tenor and baritone saxophones around 1900. While the soprano, alto and baritone saxophones were in E♭, the soprano and tenor saxophones were in B♭. Only Heckel’s melody saxophones were in C.
Saxophones were manufactured by Heckel from 1889 to 1909.
