3 in A minor, Stiles 1.2.1.6 So3,[1] is a sonata for violin and piano by Alfred Hill.
Its music originates from his Piano Trio in A minor, Stiles 1.2.2.1 TrA (probably 1890s).
It has no precise dating, but was obviously finished after Violin Sonata No.
It was performed on 6 July 1908 at the YMCA Hall in Sydney by Cyril Monk (the dedicatee of Hill's previous sonata) and Constance Brandon Usher.
