In order to allow the retrieval with some mismatches in notes of rhythm, we define similarity measures on rhythm strings. N-grams extracted from the rhythm strings of songs are organized as an trie index structure, called L-tree, to support efficient song retrieval. Retrieval algorithms which use the L-tree allow two kinds of song retrieval by rhythm, i.e. with exact match or with similar match. Experimental results show that the rhythm string model is effective in expressing queries for retrieving songs by rhythm.
