* Alto flute. The alto flute is a larger version of the flute that plays an octave lower. It has a warm, rich tone that is perfect for playing classical and jazz music. The alto flute is a good choice for flute players who want to add a lower register to their playing.
* Bass flute. The bass flute is the largest member of the flute family. It plays an octave below the alto flute and has a deep, resonant tone. The bass flute is a popular choice for playing low parts in orchestras and wind bands.
* Contrabass flute. The contrabass flute is the lowest-pitched member of the flute family. It is a very large instrument that plays two octaves below the bass flute. The contrabass flute is a rare instrument, but it has been used in a variety of musical settings, from classical to jazz.
