Years ago, Denis Pepin made a video for beginning one-row box players. It featured about eight tunes from the repertoire of French Canadian classics -- old fashioned tunes that could be found on recordings of Montmarquette, Philippe Bruneau, Adelard Thomassin, and others. Denis carefully chose tunes that build skills -- different time signatures/tune types, minor keys, basses/chords, and possibilities for ornamentation. I initially learned from this video and then continued to learn from Denis when I had the opportunity to take lessons from him in person.
Unfortunately, this video is now out of print, and it does not look like the publisher has any plans to make it available again.
There are other videos available for beginners in different stylistic directions -- Cajun (Dirk Powell) and English (Kirkpatrick). I would like to get a sense of whether there is interest for a new video with a half-dozen beginner tunes and perhaps another half-dozen intermediate tunes. Please contact me if you are interested.
