An AMP is an instrumental piece that is usually performed by a soloist or small ensemble. A SOLO is a piece of music that is performed by a single musician. A VALSE is a type of dance music that originated in France and is characterized by its fast tempo and light, lilting melody. A SONATA is a multi-movement work for a SOLO instrument or small ensemble.
