Fine bassoon teachers are a rarity in all but cities with major symphony
orchestras and/or a university with a distinguished music department
faculty. William Spencer took up the challenge of providing material for
the serious bassoonist with The Art of Bassoon Playing, published in
1958. With William Spencer's approval, Frederick Mueller took on the
task of bringing to notice recent changes in bassoon playing, pedagogy,
and manufacture, resulting in revised edition of The Art of Bassoon
Playing.
