Wah-wah (or wa-wa) is an imitative word (or onomatopoeia) for the sound of altering the resonance of musical notes to extend expressiveness, sounding much like a human voice saying the syllable wah. The wah-wah effect is a spectral glide, a "modification of the vowel quality of a tone".

  • The wah pedal (which in many cases is probably the award-winning Cry Baby by Dunlop) is one of the most original and easily identified guitar effects in the world. Nothing sounds cooler, and few sounds transcend genres so easily as the wah pedal.
