Best Answer - Chosen by Asker: in "do re mi fa so la ti do " mode
instead of chords

This is how it was explained to me from a friend from Italy who used Do Re Mi tab instead of the chord names:

do = c
re = d
mi = e
fa = f
so = g
la = a
ti = b

Don't ya just pluck the single note rather than doing intervals or chords.
