I am an adult beginner (maybe intermeidiate) fiddler. Mostly Irish Traditional tunes. I have been using Strum Machine for ~4 years. When I am learning new tunes by ear I make a solitary A part that loops until I get comfortable, then I do the increase speed to get up to session level. I do this with the B part as well. I have a practice list that contains things like “Drowsy Maggie A, Drowsy Maggie B, Ger the Rigger A, etc.”.
I also play with several others monthy at an assisted living home. Several of the tunes in our set are backed by tracks I made from SM. I usually put a 2 measure intro, then into the tune.
Thanks, this is really helpful to me and my group.
