Jazz Trombone Tip: I've been pondering on articulations as of late and wanting to share a theory that will hopefully help you all acheive a high degree of clarity and vocal quality in your trombone playing. I think of three components serving separate roles yet working in conjunction. 1.The attack — tongue 2. The breath — energy underneath the attack 3. The vocal syllables — a,e,i,o,u | Dah, Doh, Dee, Doo | Tah, Toh, Tee Air + Tongue + Vocal = Sound The tongue consonants gives you the speech. Air is the fuel. The vocal tract provides a variety of color and texture to pitch. Experiment with these concepts on intervals scales, and arppegios. The horn is the amplifier. It's up to you to wake the instrument up. Peace & Keep Swinging, Andre Hayward
