I tongue block too. I also employ a technique passed to me by Rod Piazza, who claims he got it from George "Harmonica" Smith. When playing chromatic, Rod told me to get the instrument as far back as is comfortable, it helps facilitate chords and greatly enhances tone. I was hooked the first time I tried it.
I do both. Tongue block chromatic when I try a bit of vamping. Often pucker for playing just single notes. Sometimes both during a song. Need tongue block when practicing corner switching. Nearly always pucker on Tremolos.
So I think we need to be versatile to demonstrate we can handle our harmonicas. I’ve still to master bending. Can bend from a note but can’t while playing hit a bend note.
I've yet to try TB, did manage a couple of bends when I had a go the other week, (on diatonic). Maybe it's time to try out TB on diatonic, as I'm sure it'll be a messier way of playing, especially learning.
Thanks, just checking if I'm going about it the right way.
Think I remember hearing to use the fat part of our tongue for the split chords, just wasn't sure about the single notes
.....I did learn that pressing the button can be quite the whisker grabber/ puller...ouch.
(I finally make my debut with it tomorrow at an assisted living place not far away)
