A diminished triad is a type of chord made up of three notes: the root, a minor third, and a diminished fifth. For example, in a C diminished triad, the notes are C, E♭, and G♭. This chord has a tense and unstable sound, often used to create a sense of suspense or resolution in music. Diminished triads are commonly found in various musical genres, including classical, jazz, and pop. They can function as passing chords or lead to other chords, enhancing harmonic movement. Musicians often use them to add complexity and depth to their compositions.
