Clarinette D'Amour

The clarinette d'amour is a musical instrument, a member of the clarinet family. In comparison with the B♭ and A soprano clarinets, the clarinette d'amour had a similar shape and construction, but was larger, usually pitched in G. (Examples in A♭ and F are also known.) However, it had proportionally smaller tone holes and bore, and a pear-shaped or sometimes globular bell (called 'Liebesfuß') similar to that of the cor anglais; these features gave the instrument its distinctive timbre.
