What SightSinger is
SightSinger is a web service that turns MusicXML sheet music into singing audio demos through a natural-language chat workflow. It is designed for score-led work: choir and worship leaders can make section references and part-learning demos, including split SATB parts, while teachers, songwriters, arrangers, and independent singers can hear a score performed. SightSinger recommends MusicXML files (.xml or .mxl) exported from MuseScore, Finale, Sibelius, Dorico, or Logic Pro. Its multi-track player supports live score highlighting, repeats and endings, per-track mute, solo and volume, instrument sound changes, and mix downloads. Users can add movable-do or fixed-do solfege, including la-based or do-based minor options. The service says it detects lyric language and supports Mandarin Chinese, Cantonese Chinese, Japanese, Thai, English, Spanish, French, Italian, Portuguese, and European Portuguese. Vocal rendering uses one credit per 30 seconds for each vocal part each time it is rendered; MIDI accompaniment uses one credit per two minutes per uploaded score. SightSinger says it is for demos and rehearsal tracks, not full studio production.
