I play guitar,heavy metal, and classical piano and have for as long as I can remember. I am also dyslexic. Letters and numbers look different to me, like they move and most are in reverse. I struggled to learn to read sheet music and I still write in the notes and just memorize it. Oh but with the guitar it's much easier. Google free guitar tabs. If you don't know guitar tabs are numbers on 6 lines, for example: if on the 3rd line down it has the number 2, it means your finger goes on the 3rd string in the second fret. I know this sounds complicated, it isn't, I can't give instructions well to save my life. But I still use tabs to learn guitar and I don't lose any sleep bc I don't know the names of each note. Doesn't matter how you reach the end of the rainbow, just as long as you get your pot of gold.
