Arrr Tomas Tallis, English spiritual music at its best. John P hits the nail on the head. I'm self taught and consider any human music mine to play if I like it. The resources available to modern musicians are colossal and from every culture and tradition. We are lucky to live in times when musical boundaries are breaking down and musicians like myself can have experience playing ( in my case) Trad dance, Blues, North Indian classical, Reggae, and Rock. I have no trouble getting my head round Tallis, and Lead Zeppelin. Just keep playing. All the best PP.
