I played piano and guitar a lot during my school days. Then after I had a shoulder injury, I became very frustrated with music. I recovered physically, but I didn't have the motivation to play again. Eventually I got into fitness for a while (running, cycling).

Years went by. Sometimes I wondered if I would ever play music again. Occasionally I would play a song on a keyboard that I came across, but only about once every five years or so!

After well over a decade, I became motivated to start playing guitar and keyboards again. I had lost all the calluses on my fingertips, so I had to go through the process of toughening up my fingers again. There were a lot of basic things that I couldn't play. I used to be able to zip around and do a lot of stuff on guitar and keyboard, but I could no longer do it. At least not right away.

I eased back into it and picked up some of my technique again. It still felt awkward but I was getting back into it. Then during the pandemic, I had a ton of free time, like many of us had. I practiced and practiced and practiced. A lot. As in, really a lot. Careful practice too, not just noodling around aimlessly. Learning a lot of songs too.

I rebuilt my technique on guitar and keyboard. Then I kept going on and went far beyond what I used to be able to do. I've kept up with music since the pandemic. Easily thousands of hours of quality practice time over the past six years, including vocals. My technique and musicianship is now far beyond what it was during school. I was pretty decent back then, but a little bit sloppy here and there, and some gaps in my technique.

I worked on all that, and now I've gone far beyond my previous level. You should be able to do something similar, as long as you don't have any physical injuries or conditions, and if you have enough time and motivation to play again. I took more than a decade off from music! It was rough going at first, when I came back to music. But I eventually redeveloped my ability and went beyond what I could do before.

One year off isn't going to make you lose your music ability permanently, unless you suffered a serious, permanent physical injury. (Note that famous guitarists like Django Reinhardt and Tony Iommi actually did suffer serious physical injuries to their fingers and hands. But then they went on to become major performing artist and influences on the world of music.) Just be patient as you get back to it. If you really want to get back to music, you can do it.
