The Scots Musical Museum is perhaps the core canonical collection of Scottish song, with over 200 of its 600 songs claimed for Robert Burns. This is the first research edition of the Scots Musical Museum in its entirety in over two centuries, and the first ever edition of the first edition of any kind, unearthing hundreds of previously unacknowledged variants between the first and 1803 editions. It claims that up to fifty songs should be removed from the Burns canon, and is a landmark text for understanding the history and development of Scottish song and music. A full and detailed introduction sets out the social, textual, musical and historical context in which Robert Burns and James Johnson worked, while extensive notes on the songs provide a detailed history and context of each one, and a brief critical analysis of some of the most famous of these songs. A comprehensive glossary is also included.
