What are piano chords?
Piano chords are combinations of notes played simultaneously on the keyboard. They form the harmonic foundation of a piece of music and are vital for creating texture, depth, and emotion in a composition. Chords can consist of as few as three notes (two notes are considered intervals) and typically consist of 3 or 4 different pitches, with some pitches occasionally being doubled or omitted.
Chords play a pivotal role in piano playing, serving various functions such as:
- Establishing harmony: Chords provide the harmonic context for the melody and help to define the tonality or key of a piece.
- Accompanying melodies: In many piano pieces, the left hand plays chords to support and complement the melody played by the right hand.
- Creating texture and interest: The use of chords adds layers and depth to a composition, creating a rich and engaging musical experience.
- Enhancing emotional expression: Different chord combinations and progressions can evoke specific moods and emotions, allowing the pianist to convey a wide range of feelings through their playing.

How to build chords on the piano
Chords are built using a combination of notes from a particular scale. The most common chords are triads, which consist of three notes.
The anatomy of major chords
Major triads begin with the root note (the first note of the chord), then add the note a major third (four half steps) above the root, and finally, the note a perfect fifth (seven half steps) above the root.
