Croonings, which refer to soft and melodious vocalizations, can be synonymous with various other terms. Some of these include warbling, trilling, cooing, humming, and murmuring. While warbling and trilling are typically used when describing the singing of birds, cooing and humming are more often used when referring to the sounds produced by humans. Murmuring, on the other hand, can refer to any low, indistinct humming or muttering. Regardless of the specific synonym used, croonings are generally associated with soothing, peaceful, and gentle sounds that can evoke feelings of tranquility and relaxation.
