I'm assuming you mean the D chord sounds flat in pitch right before you release it. If so, then . . .

[quote=devy99]This is more noticeable with chords where I have to fret more thinner strings. It's not noticeable with barre chords. Perhaps fretting too hard?

Maybe. If you are pressing too hard, then release pressure, then the string will go down slightly in pitch.

But here's the rub: why doesn't it sound sharp when you are playing the chord in the first place?

A guitar that is set up properly will sound in tune if you apply just enough pressure to fret the note. Any more pressure will usually make the string sound sharp. Because you are pressing too hard & pushing the string into the space between the frets into the fingerboard.

If you release pressure, then the chord stops ringing. You need to get off of those strings, mute with your strumming hand if necessary, then fret the next chord.

And how long are you holding on to the notes of that D chord before you make the move to the G chord?

One other thought, I've seen an occasional student press or pull so hard on the body or neck of the guitar that it goes up in pitch. Then when they release pressure to change chords they release the leverage or pressure they are applying to the body (with their strumming arm) and, or the neck (with their fretting arm), the strings go slightly flat for a brief moment.

But again, this makes the chord noticable sharp in the first place. Make sense?
