Classical Piano Chords
Tonal music is built from triads and the sevenths that connect them, plus the diminished chords that let a piece slip between keys. These are the chords behind the standard repertoire and behind every harmony exam, and they are worth knowing by their function as much as by their notes.
72 chords carry this tag, across 6 chord types: major, minor, diminished, suspended 4th, diminished 7th, dominant 7th flat 9. Each one has its notes spelled for that key, a fingering worked out from its own shape, a staff, and a keyboard you can hear it on.
Triads
Three notes. Every one of these is playable with one hand from day one, and between them they cover most of the music anybody starts out learning.
Major Chords
The most common chords in music. Major chords sound bright, happy, and resolved.
Minor Chords
Minor chords have a darker, sadder, and more contemplative sound than major chords.
Diminished Chords
Diminished chords sound tense and unstable, often used as passing chords.
Suspended 4th Chords
Suspended 4th chords create expectation and are often resolved to a major chord.
Seventh chords
A triad with a fourth note stacked on top. Sevenths are where harmony stops being just bright or dark and starts having a direction it wants to go.
Diminished 7th Chords
Diminished 7th chords are highly dramatic, a favorite in classical and jazz.
Extended chords
Ninths, elevenths and thirteenths. These are wider than one hand, so each page shows the two-hand voicing a player actually uses rather than a stack of five notes in a row.
Dominant 7th Flat 9 Chords
Flat 9 chords are dark and urgent, and they pull hardest into a minor chord.
