Associated with his MandoLessons site is a Patreon page where for as low as $1 a month you can become a Patron and help support his MandoLessons initiative. Patreon is kind of like Kickstarter, but instead of helping fund a one-time project, Patreon allows you to help sustain an artist's ongoing work by contributing at a "name your price" level on a monthly basis. On Baron's Patreon page he offers varying incentives to Patrons who donate $5, $10, $15 or $20 or more per month. For example, Baron will give the next five donors at the $10 per month level a one on one lesson in person or via Skype or Google Hangout. I took him up on this and really enjoyed the lesson and the generous amount of time Baron spent with me.
Baron's YouTube channel is even more extensive, with a wide selection of 150+ fiddle tunes in a variety of styles including Irish jigs and reels, oldtime, Quebecois and Cape Breton, Scandinavian, contradance tunes, original compositions and more. I particularly like his videos of the tunes Road to Malvern and a special version of the Irish tune Morning Star in F (usually it's in G).
(check out their album here) and is also a regular instructor at the esteemed Maine Fiddle Camp. His partner in Velocipede, fiddler Julia Plumb, also has a pretty nifty YouTube profile with some fiddle instruction videos and she also teaches at Maine Fiddle Camp. As a recent fan of their music and teaching style, I can tell you that Baron and Julia are two young traditional musicians to watch out for!
The fact that Baron's MandoLessons site is free is a great thing, for sure. It provides a resource for those on a tight budget to learn more about playing music. Although, if you can afford to make a contribution, you might consider becoming a patron to help support this great work he is doing. Even at $1 or $5 a month you're helping make a difference without breaking the bank!
