• relax
• reduce left arm pressure on chops
• think open and relaxed above the staff
• use the lower 8ve as your guide to match sound and feel
• practice with a trombone in unison 8ves (1 etude a day 15-20 min)
• as an alternative record yourself 8vb and play along with it
• rid on the sound of the other player (let them to the work-play off their sound and overtones)
• use his sound to allow yourself to relax and play more easily
• hear that lower 8ve sound fully in its absence (when playing alone)
• generate an excellent sound quality even at higher volume and range
• move air through all notes-don't let up even for a second (following a slurred passage or dotted rhythm)
• give all notes direction
