Miniature harmonicas are not just original gifts, but full-range C major instruments that are perfectly playable - even in zero gravity!
On December 16, 1965, the Hohner "Little Lady" made its first appearance in space. Astronaut Walter Schirra played "Jingle Bells" on this harmonica, which he had smuggled aboard the Gemini 4 spacecraft. The harmonica thus became the first musical instrument in space.
