ADAGIO (ad-äzh'ē-ō), a slow or very slow movement or measure of time in music. The distinctive feature of the adagio being its power of expression, it affords the most direct means to the composer of manifesting his individuality of feeling. The finest specimens of the adagio are found in the works of the old masters, above all in Beethoven.
