i came across this ear training tutorial, that teach us how to listen to music intervals, i dont know what is it for but I just learn it.. is it useful or i can just learn other more important stuffs first like minor and major scales.

Good knowledge to learn especially when composing/covering, u'll notice later minor/major need to play around 2,3,4,5 key notes to get it work in harmony Learn about Sharp/Flat notes too, some ppl tune their guitar in Drop C Sharp but tuner showing Drop D Flat and panic lol

Alright thanks leaseliner! I'm now learning how to listen to major 6th, major 7th, and perfect octave, so frustrated when I can't get it right, but I'll be there someday. Thank you!

Don't give up!

Thank you Daniel!
