I'm really seeing myself become a guitarist, and I'm enjoying it. some brave souls dare say online they find enjoyment and usefulness out of music apps. there seem to be some agreement on a few good beginners books. YouTube is too distracting and unstructured for me. But I probably average 2.5 hours of practice a week, I insist on gold-starring everything before I move on, and I blend progressing through the learning tree with the exercises/work outs section (scales, chord trainer, etc) and after each level I learn a few extra-curricula songs I like from that level to really bed in the skills. Here is what I found: r/piano hates apps like Yousician or simply piano.
I can play guitar well enough now to play songs I thought it'd take me years to crack.
Ha! I was afraid perhaps this might be the music equivalent! But I have had Premium for about a year now and been learning on YouSician for about a year and a half in total, and I've kept on improving.
So I didn't know a single chord or anything before I grabbed Yousician (free version at first) and I was a little apprehensive at first because I once tried to learn French via Duolingo and after hours and hours of dedication I can confirm I still can't speak a word of French.
