Pucker on! I've been playing for fifty year and I prefer the pucker. I just use tongue blocks for split chord intervals which sound cool when followed by single note puckering in the middle. My playing is also influenced by experience on the clarinet and sax. I like to use a lot of individually tongued notes with lots of bends in between. Just love how the harmonica lets you play the "blue notes"--the not quite minor third and sometimes the not quite minor fifth. In other words, on a c harp played crosswise in the key of g, the almost b flat, imperfectly written as -3' or the almost d flat a little below -4'. I think those are among the coolest notes ever! If you can master playing the basic blues chords (g7,c &d) and then just try random individual notes. You're sure to hear yourself playing some interesting sounds before long. Then start tabbing so you can remember your discoveries. Just keep on playing. By the time you blow out your first reed, you'll have learned a lot. BTW, if you want to improve brain function, just turn your harp around (high notes on the left). I've tried and failed, but it is supposed to be a brain expander
