Hey Keith, I am really glad that you posted these two videos. For a beginner you are doing quite well. Just keep playing, even if it's the same song over and over. The more you play, the more familiar you become with the harmonica and the better player you become. Remember that no one was born knowing how to play a harmonica.
Well done Keith! I'm glad I stopped by here to check these out.
Posting your first recordings is hard, but a great step forward in boosting your confidence. In time, you can post further recordings of the same tunes and you'll notice how much you've progressed.
My only suggestion at this point would be to either keep the microphone on a stand, or just play acoustically instead. That way, you can hold the harp with two hands and hopefully be more relaxed and that might ease the learning curve. Just a humble suggestion of course, but speaking from my own limited experience, I found that having a comfortable hold on the harp with both hands aided muscle memory and made it easier to be more accurate.
Keep up the good work, I look forward to hearing more from you.
