For todayâs Vault Series video, hereâs the Allegro - the 3rd movement from Joaquin Rodrigoâs Sonata Giocosa (playful sonata). The Sonata Giocosa (playful sonata) is a more light hearted take on the typical classical era sonata form. Rodrigo often uses flamenco elements in his music like rapid, fiery scales passages and rasqueado strums. The 3rd movement takes shape as a zapateado. But it also incorporates the BulerÃas rhythm. (Think the 3 against 2 rhythm in the song âAmericaâ from West Side Story)
