Yet another delightful addition to the Dummies series on Music. I approaching Theory with some students, as there is already some distant memory, probably from siblings or peers, that 'Theory is Dull', and for the ABRSM is a compulsory unit before moving on to the Grade 6 practical examination. Also, arguably, Theory is decidedly useful for those undertaking GCSE & A-level.
I've been collecting different books on Theory, and this is by far the most approachable, and indeed the most useful. Typically for the series, it is set out in a readable, logical format, focussing on history of theory, and then moving from the staff to intervals, then scales and finally form. I do love their attempt to make theory relevant, with the information on important theorists. Also, the CD is hugely useful, in the days of multimedia learning.
A must.
