Sympathetic chord is a term often used in music to describe a chord that resonates with the same frequency as another instrument or object nearby. However, there are several synonyms for this term that can be used to describe the same effect. For example, sympathetic resonance, sympathetic vibration, and sympathetic tone are all commonly used phrases in music to refer to the phenomenon. Other synonyms include connected resonance, sympathetic strings, and sympathetic harmonics. Each of these terms describes a similar effect, where one object resonates with another due to their harmonic frequencies aligning.
