As a composer Mudie's successes were mainly confined to his earlier years. While a student at the academy his song "Lungi dal caro bene" was thought so meritorious that the committee paid the cost of its publication. Several vocal pieces with orchestral accompaniment, and symphonies in C and in B flat, were also composed while he was a student. The
Society of British Musicians gave him much encouragement, and at their concerts there were performances of a symphony in F (1835), a symphony in D (1837), a quintet in E flat for piano and strings (1843), a trio in D for piano and strings (1843), and several songs and concerted vocal pieces. While in Edinburgh he composed a number of piano pieces and songs, and wrote accompaniments for a large proportion of the airs in
Wood's Songs of Scotland. His published music consists of forty-eight piano solos, six piano duets, nineteen fantasias, twenty-four sacred songs, three sacred duets, three chamber anthems for three voices, forty-two separate songs, and two duets. The existing scores of his symphonies and all his printed works were deposited in the library of the Royal Academy of Music.
George Alexander Macfarren wrote in
A Dictionary of Music and Musicians (1900): "In the obscurity of provincial practice as a teacher Mudie seems to have lost incentive to artistic exertion, and with the incentive almost the power. He must be regarded less as a musician of promise than as one of fulfilment, and it would be highly to the credit of any concert-giving institution of the day to unearth some of those works...." ==References==
