Giacomo Puccini composed Gianni Schicchi in 1918. It was the third opera of Il trittico (a trilogy). O mio babbino caro is a famous arietta sung by Gianni Schicchi’s daughter Lauretta. The song is very melodic and it has a beautiful harmonization. This arrangement is ideal for smaller bands or bands missing certain players as it offers alternatives for many parts and will make an ideal encore.
