theory; correction

[Dave Nereson]

    String players will (unconsciously sometimes) play F# sharper than G flat, if the F# is in a dissonant chord that's resolving to a consonant one, that is, if the F# is a seventh resolving to an octave or an augmented 4th resolving to a "perfect" fifth ("perfect" meaning that it's not diminished or augmented, even though on the piano, it may be contracted from a perfect 3:2 beatless fifth).  F# and G flat, in equal temperament, may be the same frequency, but to make sense musically in terms of key signature and chords, they're not interchangeable.
                                                                                        --Dave Nereson, RPT & former music major
Woops, I meant augmented 4th resolving to a minor 6th (in the case of a dominant seven chord resolving to the one chord, e.g. (bottom to top) D-C-(D)-F#  to G-B-(D)-G.  The C-F# is the augmented 4th (dissonant) and it resolves to the minor 6th B-G.  But that minor 6th is part of a Major chord.      --Dave Nereson
