Bruch has only string concertos (mainly violin and also cello) and viola/clarinet/piano trio in this game. Elgar - cello concerto, orchestra, march, vocal (with orchestra and piano). Bruch is more simple, romantic, trills, coloratura. But Bruch Kol Nidrei is a more serious cello concerto. Elgar is more serious, post-romantic, wide, complex, orchestral. But Elgar also has dancing Serenade. Cello concertos can be most difficult to guess in this game. (Bruch, Elgar)

Bruch has only violin and cello concertos and clarinet/viola/piano trio in the game. All other goes to Brahms (vocal, piano, orchestra, dance, chamber). Statistically most of string concertos in the game will belong to Bruch. String melody in Brahms string concertos sounds more linear, repetitive, serious and less light, romantic, coloratura. (Brahms, Bruch)

Bruch - piano, romantic solo strings. RV Williams - emotional, english folk, energetic, oriental, atmospheric. RV Williams also can have solo strings, but they sound more linear and oriental. (Bruch, RV Williams)

Piano is Bruch. Bruch was born 14 years after Bruckner, but Bruch is romantic solo strings, while Bruckner is post-romantic, complex, serious, polyphonic. Bruckner romantic parts are more often for solo woodwinds. Bruckner also has close to romantic solo string sounds in his mass and some symphonies, so listen longer to string pieces. Bruckner uses harp only in Symphony 8 with string pizzicato and without those long arpeggios like Bruch. (Bruch, Bruckner)
