Speed with Bends - Articulation Series
When you play fast it's best to articulate the second note of each pair. For example, If you're traveling up the harmonica playing 4' 4, articulate the second of the pair, 4 (= 4' 4KA)... when traveling down the harmonica you'll articulate the second note again, 4' ( = 4 4'KU). Try the two examples below to get this idea. Start slow and then build up speed with practice.
1) 3" 3 4+ 4' 4 6+ (3" 3KA 4+ 4' 4KA 6+)
2) 6 6' 6+ 5 5' 5+ 4 4' 4+ 3' 3" 2 (6 6'KU 6+ 5 5'KU 5+ 4 4'KU 4+ 3' 3"KU 2)
You can use TA (TU for bend) in the place of KA as well... expriment with both.
