Calculate the frequencies of all tones in a chord from its root.
A chord stacks selected scale degrees above its root, and each tone's frequency follows from the equal-tempered step. Laying out chord tones in hertz helps sound designers tune all voices of a chord to the same reference.
Chord Frequency
Each chord tone = root x 2^(scale degree / 12)
