Workshop Instructors
Dennis Cooper

Dennis Cooper helped establish the Idaho Harmonica Workshop in 2016 and was the first instructor.  Dennis was strictly a rock & blues harmonica soloist before 1998 when he ventured to Yellow Pine for the first time to see what it was all about. That’s when he met a fellow player who played in the blues style but captured the melody with more feeling than traditional 1st position players. He has expanded his playlist of 2nd position melodies from the “Steel Guitar Rag” in 1998 to over 200 songs to date.” Three (maybe 4 if I get it done) albums later he’s still adding “impossible” songs to his playlist. From Big Band to Reggae, with a little Country & Rock-N-Roll thrown in for good measure you’ll hear it all during his shows.”
