I often find that when I'm strumming chords, even when my fingers on my left hand are all correct it either sounds to harsh or to weak, so I'm wondering if there is proper technique to strumming that I'm missing out on?
How are you strumming now? I find it best to use mostly the wrist for speed, and the elbow to just give a bit of volume.
Bruh? Brah? Breh? Bruae? Bruae.
Have no idea what too weak sounds like... does each string ring clear? Are you hitting every string? Using a pick or not?
