This study looks at Jehan Alain's music itself. However, it does not propose to analyze every bar of every composition but rather to point out certain melodic, rhythmic, and harmonic traits that are peculiar to this composer's style. It will also set forth facts concerning Alain's registrations and other items of special interest to organists. Upon such investigation an attempt will be made to reach a critical evaluation of Alain as a composer for the organ.
