For Philipp, Saint-Saëns was the revered teacher he first sought guidance from in Paris during his youth. Saint-Saëns, in turn, placed great trust in Philipp, who had achieved success as a pianist, dedicating works to him, and their friendship continued throughout their lives. Saint-Saëns' concertos, chamber music, and piano works constituted Philipp's most important repertoire and life's work. What is surprising is the fact that Philipp, despite being a prolific arranger, undertook very few arrangements of works by his revered Saint-Saëns. Compared to his arrangements of major works by Widor and Théodore Dubois, one cannot shake the feeling that this is somewhat insufficient. It is speculated that the relationship between Saint-Saëns and Philipp was so close, as a master and disciple who understood each other well, that it might have led to a certain deference towards publishers or other parties.Lullaby, Op. 105, is a four-hand piano duet from Saint-Saëns' later period, characterized by a simple style devoid of ostentation, a warm melody, and a delicate harmonic language reminiscent of Fauré. Andante quasi Allegretto, 2/4 time, E major. Philipp's piano solo version retains the original's profound charm while being adapted to be comfortably playable with two hands. It can be considered a valuable arrangement by a distinguished pupil who was thoroughly conversant with Saint-Saëns' pianism.
