Where do I find exercises or songs to practice?

Franco: I'm not certain I understand your question, but: Have you watched the video on the home page, "Watch Me First! How to Navigate Bluesharmonica.com"? It will give you a roadmap for how to use study songs, exercises, lessons, etc. on this website. The lesson links include printable PDFs of charts (in both musical notation and harmonica tablature) and video lessons. If that doesn't answer your question, you might try re-posting your question in the "Ask Harmonica Instructor David Barrett" thread in this Forum, to get a discussion going with David, who will be able to answer any questions you may have. Best wishes for a fun time learning.
