What's the scoop on "scoops"?
Instruments- discuss specific features, luthiers, instrument problems & questions
"Scoops" (scallops) are not necessary to get good sound or volume from a dulcimer. Some people just like them and think they improve the sound of the dulcimer. Scallops free up the soundboard because the fretboard only contacts the soundboard in a few small areas. Some builders will also channel-out the center of the fretboard as well, to create even smaller contact areas.
Do I scallop my dulcimer fretboards? Nope-- never have. But I DO channel them, almost every time. Some Tennessee music boxes have "false scallops" on the sides of their fretboards, but they're just notches for decoration -- they don't go all the way through the fretboard.
