When assessing the quality of a brass instrument the player must consider
a number of factors, the main consideration being the playability of the chosen
instrument. The playability of an instrument is a broad term used to describe
how well the instrument plays; this includes how in tune the resonant modes are,
how easy it is to start and move between notes, how easy it is to bend notes and
the degree of spectral enrichment during a crescendo that is able to be produced.
