Otilie Suková was the daughter of Antonín Dvorák and the wife of Josef Suk. A gifted musician, she played the piano and wrote several compositions of her own, inspired by her musical surroundings. Four of her piano pieces have survived; Suk wrote them down after his wife's performance. "Lullaby", "Humoresque" and "Joey on the Horsie" were published four years after her death as a supplement to the periodical Zlatá Praha. "To Dear Daddy" appears here for the first time in print. It is based on two manuscripts; the first is Suk's manuscript, the second is Otilie's clean copy of Suk's manuscript.
