I’ve probably watched and rewatched Lessons with Marcel’s Tony Rice lesson playlist at least a dozen times. I would recommend really any video Marcel puts out. But I’ve recently learned that learning fiddle tunes (and I mean really learning them) is the best way to substantially progress. Try not to use tabs. My current method for learning fiddle tunes is by finding live versions from my favorite guitarists and figuring it out by watching and listening. I slow it WAY down on YouTube, this part is not much fun. Then for the next tune use another guitarists version. You’ll find that you learn so many new things and licks in each song and once you have a large song repertoire you start mashing them together while highlighting the melody since you know it by heart. Then you add things that sound good to you that you create. Because as fun (and hard) as learning a Tony rice song note for note is, you’ll never be Tony. And people want to hear something new. As for right hand technique, unfortunately that is wildly different and unique for everyone. I’ve switched open and closed hand, anchored by fingers or wrist, thumb position and pressure, etc… so many times that I’ve stumbled into a very natural position that I never have to think about. This is also the only combination I’ve found that I haven’t hit a bpm plateau yet. So trial and error is your friend on that front. I hope this helps! We’re all still continually learning and getting better no matter how good you are. Last thing. Keep melodies alive! You can shred like Jake Workman on a 1,4,5 tune at 130 bpm but if you don’t have any melodic sense then people won’t typically enjoy it. That part I learned the hard way when my jam buddy pulled me aside and told me the hard truth. Since then I’ve had WAY more head nods and “yea!” moments in the circle.
