Many of Bowen's piano works are aimed at improving piano technique. One of his most notable works, Twenty-Four Preludes, Op. 102, is set in all major and minor keys and his Twelve Studies, Op. 46, are also intended to address different elements of piano technique. Bowen dedicated the studies to his piano teacher at the Royal Academy of Music, Tobias Matthay, who had written several books about various aspects of fore-arm rotation and piano touch. Each of Bowen's studies deals with a different aspect of piano technique discussed in Matthay's books. Inspired by Matthay's innovative approaches, Bowen later produced two books on piano technique: "Pedalling the Modern Piano Forte" (London, 1936) and "The Simplicity of Piano Technique" (London, 1961)
