Thanks Luke! I am a Tongue Blocker and whenever I have tried to learn to pucker or lip block I could not learn to play single notes clearly. I have now watched the first part of Luke’s video Harmonica Single Notes for Beginners (+ Learn "Low Rider") - YouTube and already can play ‘Danny Boy’ with almost completely clean single notes. I have no doubt that, with just a little more practice, I will be able to play using lip blocking, with clean notes,
Woo hoo! Congrats, @frankyb. Glad the vid helped! Yes, I think knowing both techniques is optimal in the long run.
