Bebung

:"Bebung may also refer to a musical composition by Michael Jarrell.""Bebung" (German: "a trembling"; IPA2|ˈbeːbʊŋ) is a type of vibrato executed on the clavichord.

When a clavichord key is pressed, a small metal tangent strikes a string and remains in contact with it for as long as the key is held down. By applying a rocking pressure up and down the key with the finger, a performer can slightly alter the vibrating length of the string itself, producing a vibrato quality known as "Bebung". While the vibrato on fretless string instruments such as the violin typically oscillates in pitch both above and below the nominal note, clavichord "Bebung" can only produce pitches above the note.

"Bebung" was often not explicitly indicated in sheet music; the assumption was that, like other ornaments, "Bebung" was to be applied at the performer's discretion. Where "Bebung" is indicated, it appears as a series of dots written above or below a note, with the number of dots indicating the number of movements of the finger.
