The Sandner184 Solo Alto F is a flapless marching flute with highest precision and tonal purity. It is the first purely cylindrical flute in the world and has a range of around three octaves and the characteristics of a concert flute. The full, pure tone of the fundamental notes and the octave registers enable excellent interplay with other instruments, for which Sandner flutes are renowned. The mouthpieces of the different sizes have been optimised and now have an improved response.
