5/9 LEAN ON ME- The Bridge has two parts. Either: 1.) Percussive “Zed” strum: The left-hand mutes the strings lightly, like a cloud. "Knock, down-up" strum. Or 2.) Clap on Ct #2 & Ct #4. At 07:40 Students took turns clapping. Instantaneous pa’ani! At 13:35 Breakthroughs! At 17:10 Played entire song.
