In Hindustani music, meend (Hindi: मींडْ ْ, ) refers to a glide from one note to another. It is an essential performance practice, and is used often in vocal and instrumental music. On the veena, sitar, and other plucked stringed instruments, it is usually done by pushing the strings across the frets to vary their effective length and tension; compare portamento and finger vibrato. This can be done on wind instruments like the bansuri by using the fingers to cover the holes in a manner that the changes between discrete pitches are imperceptible. It is considered a sort of alankar, or ornament.
