I play anything from Tom Jones to Metallica. And I don't shred. I don't think you need sweep arpeggios and string skipping and exotic scales to play "Delilah" or "I Want To Hold Your Hand" or "Rise" or "Pride And Joy".
I started playing pop, classic rock and blues which requires a very firm grip in the neck and heavy hand. Shred requires fleet fingered players. Mabigat kamay ko, so even if I try to learn how to shred, mediyo may kahirapan.
