There is much more to a key signature than just Major and relative Minor tonalities. "Goslings" is a book of 42 piano concert preludes written in every mode of every sharps key signature up to 5 sharps; and all without accidentals. It explores the vast variety of colours and textures that can be found in the seven contrasting modes of each key signature. "Goslings" is suitable for intermediate to advanced pianists. It is a great aid for those who wish to advance their keyboard navigation skills.
