The saxophone was created around 1846. Sax s primary key work was very basic which made wide intervals quite hard to finger. Because of this, many developers and instrument makers added alternate fingerings and more keys to make playing less difficult. One of the most significant advancements in its key work was that both tone holes can be controlled by the left thumb using one octave key. Blowpipes today usually have a non-return valve so that the player does not need to cover the edge of the blowpipe with his or her tongue when inhaling.

A consort of crumhorns is a cluster of instruments with different pitches and sizes. Crumhorns are meant to copy the vocal quartet with bass, tenor, soprano, and alto. It has pitches in F and C. The instrument has a naturally sharp sound that gives a good effect in the modern ensemble. The tone which is from nasal humming to rich buzzing depends on the way their reeds are voiced.
