A fragment of ‘lost’ music found in the pages of Scotland’s first full-length printed book is providing clues to what music sounded like five centuries ago. Scholars have been investigating the origins of the musical score — which contains only 55 notes — to cast new light on music from pre-Reformation Scotland in the early sixteenth-century. Researchers say the tantalizing discovery is a rare example of music from Scottish religious institutions 500 years ago, and is the only piece which survives from the northeast of Scotland from this period.
