Scordatura repertoire
Bach Suite No. 5
C2 G2 D3 G3
The A string down to G — the most famous scordatura there is. Darker resonance, and chords the standard tuning can't reach.

Kodály Sonata
B1 F♯2 D3 A3
Op. 8 tunes the bottom two strings down a semitone to B and F♯, so the open strings sound the B minor world of the piece.
