Continuous alternating low and high pitched laughter

A rhythmic pattern of laughter streams into your ears, shifting constantly between low, rumbling chuckles and high, piercing giggles. It's a continuous, alternating cycle of different laughter pitches, echoing a sound akin to 'wa-wa-wa'. The laughter seems to be in response to some unfortunate outcome, a situation that doesn't quite go as planned. You can almost hear the 'oh-no', 'oops' in the tonality of the laughter, a reflection of a mistake or a fail that's occurred. The undesired outcome is almost palpable in the sound, yet there's a sense of humor in the laughter, an accepting acknowledgment of the error. The laughter carries a rich narrative of human imperfection, failure, and the ability to find joy in it.
