An excellent little book that covers all the essentials of modern, standard music notation. It's very well presented and laid out - the text is very clear and there are numerous music examples which only add to the clarity. Early methods of notation, such as neumes, exotic modern notation techniques (for example for aleatoric or electronic music) and notation for non-western instruments are not covered. Tablature for string instruments such as guitars is dealt with briefly but adequately. It's also small and so, easily portable. Recommended.
