Smith - Digital Sheet Music #W29111OB. Published by David E. Smith - Digital Sheet Music (DX.W29111OB). Written in typical passacaglia (theme in the bass line) and Fugue fashion, the theme is presented in the piano. The first variation is a gently modified tune in duple with the accompaniment in triplets. In variation two, the tune is rhythmically altered while the upper accompaniment is presented in a spritely fashion. Variation three, the tune is in a triplet moving nature while the theme is in block harmonization in the accompaniment. Variation four is expressive in an almost cadenza fashion. Finally, the Fugue is in a lively four voice manner, ending with a strong proclamation of the title, itself.
