The term 'SAX OR FLUTE TYPE' can be summarized as an ALTO, which is a four-letter word. An ALTO is a type of musical instrument, either a saxophone or a flute. Saxophones and flutes are both woodwind instruments, meaning they produce sound when air is blown through them. ALTO saxophones and ALTO flutes are both smaller than their counterparts, the tenor saxophone and the concert flute, respectively. They are also pitched in a higher range than their larger counterparts.
