What does ∆ mean in music?

The triangle symbol Δ originally meant “triad” (meaning major triad) [1]. However, nowadays it is – at least to my knowledge, and when used without any other qualifiers – exclusively used to denote a major seventh chord, even though that usage is a bit sloppy. I recommend you use Δ7 for denoting a major seventh chord.

What do triangles over notes mean?
