Tuning, & Equally-Tempered Tuning

Fourier Synthesis:  Process of combining harmonics to form a complex wave.

Fourier Analysis (Spectral analysis): Inverse process of determining harmonic content of complex waves.

Attack Transients:  with any musical sound beginning a unique sound(s) occur that last a brief moment.  Possess different spectrum from the steady note that follows after the attack.

Decay Transients:  For stringed instruments vibration amplitude continually decreases after the initial attack.

Coherence, & Incoherent Sources

Reflectors, Acoustic Absorbers
