Teagarden's trombone style was largely self-taught, and he developed many unusual alternative positions and novel special effects on the instrument. He is usually considered the most innovative jazz trombone stylist of the pre-bebop era – Pee Wee Russell once called him "the best trombone player in the world" – and did much to expand the role of the instrument beyond the old tailgate style role of the early New Orleans brass bands. Chief among his contributions to the language of jazz trombonists was his ability to interject the blues or merely a "blue feeling" into virtually any piece of music. [Wikipedia]

Important point to note here: was largely self-taught.

• With the Not bothered wagon empty the Disagrees will get nervous and
• Shift up the train to join the Agrees.
