Agree with Ukebert - the Tonic+5
th is a pretty feeble harmony! Bear in mind that it is a simple 2
nd harmonic. Of course Tonic+4
th in mathematically the same, but at least that's an inverted interval, and also isn't a chord of our RH diatonic scale. "So there is tension". My own 'Morris' organetto actually had G/D and C/C chords left end and with all notes both ways some really interesting effects were possible.
But this isn't about 5ths and 4ths. Its about those who feel their music as a melody line and rhythm v those who feel their music as a harmonic structure with rhythm. Both are of course correct.
BTW: Anyone for the "sensitive female progression" (Am,F,C,G) I offered on today's
backing trackthread ... Now that's
really sexy
