Not sure which forum this should be on but this seems a safe place. Tulsa will be hosting the SPAH (Society for the Preservation and Advancement of Harmonicas) convention starting Aug 13th, 2024,downtown Tulsa hotel. Maybe 500 harmonica players from all over the world to perform and study thru day classes and evening jam sessions. Both Diatonic and Chromatic harmonica playing. Free concert one night, have not been able to find in schedule which night. Jam sessions for blues, electric, country, gospil, classical. Route 66 Harmonica club in Tulsa is the sponsor this year. PM if you need additional info.
