This randomly generated multichoice quiz tests your knowledge of Neo-Riemannian triadic transformations. It tests the 4 main operations of L, P, R and S, and also adds David Kopp's extensions, M, m, F and D.

DEFINITIONS

• L = Leichtonwechsel (root change = M3 up (for maj) or down (for min), mode change)
• P = Parallel (no root change, mode change)
• R = Relative (root change = m3 down (for maj) or up (for min), mode change)
• S = SLIDE (root change = m2 up (for maj) or down (for min), mode change)
• M = chromatic mediant (root change = major third down, no mode change)
• M^-1 = chromatic mediant inverse (root change = major third up, no mode change)
• m = chromatic mediant (root change = minor third down, no mode change)
• m^-1 = chromatic mediant (root change = minor third up, no mode change)
• D = dominant (root change = perfect fifth down, no mode change)
• D^-1 = dominant (root change = perfect fifth, no mode change)
• N = ‘near’ fifth (root change = P4 up (if maj) or down (if min), mode change)
• F = ‘far’ fifth (root change = P5 up (if maj) or down (if min), mode change)
• H = ‘Hexatonic Pole’ (root change = M3 down (if maj) or up (if min), mode change)
• T₆ = Tritone transposition (root change = tritone, no mode change)

The test is timed from when you start. You should be aiming to complete this test in under 4 minutes.

0–2 mins = Professional  2–4 mins = Good  4–6 mins = Average  6–8 mins = Sluggish  8 mins or more = Too slow.
