That’s quite the foundation for a life in music!
I learnt to sing by tone, not key 
every time I try and play an instrument my head gets hot and I spaz out.
Bass is an interesting one tho. I can keep a rhythm going with a few notes and put some fkin 'tude on it.
Always tried to sing but by tone so not well.
Wrote my first rap about 11. Probably wrote a million rhymes in between now and then.
All my musical knowledge is related to production, tone, timbre, resonance etc.
Soon as it goes beyond abc: ace, ceg type stuff my mind falls out my head
and the small 3 note ditty I just wrote Ill fuck it up out of music in some punk melee.
Then it just sounds like shit, but quite well produced 
Brains are fkin weird arent they
