Piano Chord Finder Guide & FAQ

How do I read chord extensions and alterations like 9th, 11th, and 7#9?

Extensions extend the chord beyond the 7th by stacking upper thirds: 9ths (major 2nd an octave up), 11ths (perfect 4th up), and 13ths (major 6th up). Altered notes (#9, b9, #11, b5) introduce harmonic tension and dissonance prized in jazz, gospel, and neo-soul.

What is the advantage of rootless shell voicings on piano?

When playing with a bass player or in a modern mix, playing the root in the left hand can clash with the bassline. Rootless shell voicings (made famous by Bill Evans) play the essential guide tones (3rd and 7th) plus extensions (9th, 5th), keeping the sound crystal-clear.

What are Indian Sargam equivalents for piano chords?

In Indian classical music, intervals are relative to the tonic Sa. A Major triad is Sa–Ga–Pa (shuddha Ga), a Minor triad is Sa–ga–Pa (komal ga), and a Dominant 7th is Sa–Ga–Pa–ni (komal ni). This helps bilingual keyboardists map western harmony to raga improvisation.
