The Nino Percussion Mini Melody Steel Tongue Drums with 5.5” diameter are equipped with pre-tuned notes and can be played by anyone, anywhere, regardless of skill. They are especially great for younger children learning music or for teachers to use as a signal in classrooms. Their pre-tuned scale means the instrument is harmonious in itself so there are no dissonant notes to play. The sound is mellow and soothing (like a soft steel pan drum). Each drum includes two soft rubber mallets and is available as a Red or White version.
