Oh dear !!
What key was the huff in??
Some traditions revel in quarter tones (I'm thinking of some areas of Sweden) but, in general, it doesn't seem the best way to have a tuneful session.
Yes, everyone forgives (and helps) the novice, but this guy could obviously play...So, no excuse.
It would be like me playing in A flat in a room full of D/G melodeon players....!!
Ah Well, it takes all sorts!
