That's pretty cool, sniper, but I'd like to see the bass clef clearly, not just implied.
Hey Doc~ You could reverse the bass clef to make the small d too.
Use purpleheart wood for the inside of the heart thus formed. ...or redwood.
Make the lines forming d & b a color (gold, maybe?) & do the bass clef & it's reverse in black.
I did several drawings last night of various ideas I'll have to scan at Kinko's & put here.
