In
music, a
diminished triad , also known as the
minor flatted fifth (m5), is a
triad consisting of two
minor thirds above the
root — if built on C, a
diminished triad would have a C, an E and a G. It resembles a
minor triad with a lowered (
flattened) fifth. It can be represented by the integer notation {0, 3, 6}.
