The modern drum-kit has come a long way in the 110 years that have elapsed since it evolved in 1901 in the bars and brothels of New Orleans - but the principles remain the same.

Drum Kit Manual is the latest addition to the expanding list of Haynes Manuals about musical instruments, and it covers the subject in exhaustive detail with step-by-step instructions and clear colour photographs.
