The E-flat clarinet is a member of the clarinet family, smaller than the more common B♭ clarinet and pitched a perfect fourth higher. It is typically considered the sopranino or piccolo member of the clarinet family and is a transposing instrument in E♭ with a sounding pitch a minor third higher than written. The E-flat clarinet has a total length of about 49 centimetres (19 in).
