The dulcimer is an amazing instrument. It is somewhat like a cross between a violin and guitar. (referring to the mountain dulcimer here)
One has the ability to play melody with added harmony and can also play chords.
There are many individuals who use the dulcimer – whether for personal enjoyment or as part of a church service (offertory, special, etc.).
The following is a sample of music played on a mountain dulcimer.
