Saxophone Family - Composition

Composition

Music for most saxophones is usually notated using treble clef. The standard written range extends from a B♭ below the staff to an F or F♯ three ledger lines above the staff. Most, if not all, intermediate and professional saxophones made today are built with F♯ keys, with F♯ included on even student instruments. There are many models of soprano saxophone that have a key for high G, and most modern models of baritone saxophone have an extended bore and key to produce low A; it is also possible to play a low A on any saxophone by blocking the end of the bell, usually with the foot or inside of the left thigh. Low A keys however were not limited to just the baritone saxophone. For a short time Selmer Paris produced mark VI alto saxophones with the low A key. Notes above F are considered part of the altissimo register of any sax, and can be produced using advanced embouchure techniques and fingering combinations. Sax himself had mastered these techniques; he demonstrated the instrument as having a range of just beyond three octaves up to a (written) high B4. Modern saxophone players have extended this range to over 4 octaves on tenor and alto.

Because all saxophones use the same key arrangement and fingering to produce a given notated pitch, it is not difficult for a competent player to switch among the various sizes when the music has been suitably transposed, and many do so. Since the baritone and alto are pitched in E♭, players can read concert pitch music notated in the bass clef by reading it as if it were treble clef and adding three sharps to the key signature. This process, referred to as clef substitution, makes it possible for the baritone to play from parts written for bassoon, tuba, trombone, or string bass. This can be useful if a band or orchestra lacks one of those instruments.
