Hebridean Song and the Laws of Interpretation [PDF ebook] 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. As to the performance of Hebridean songs, one cannot generalise, they are so varied. They simply must always obey the laws of musical interpretation, applicable alike to them and to the songs of a Schubert and a Schumann. I stress Schubert, because in him most often a rigorously driving rhythm is exacted (as in so much of the best Hebridean song), and Schumann, because inhim a broad rhapsodical tempo rubato is essential (as in another type of Hebridean air).
