Brahms' Lullaby is one of the best known bedtime melodies in Western music, originally written by Johannes Brahms in the 19th century. Short bell, toy piano and music box versions spread widely online because the tune is instantly recognizable even in simple arrangements. This glockenspiel-style take fits modern edits well, especially for sleep content, infant videos and gentle joke setups. It remains popular because listeners quickly associate the melody with rest, comfort and the classic idea of being tucked in for the night.
