In Clif Walker’s piece Disguised, things are definitely not what they seem! in this medium-easy percussion ensemble, players manipulate their own instruments in order to create new and interesting sounds. For example, the marimba players use mutes over the bars to “disguise’’ the sound of the marimba, and the vibraphones are sometimes played with finger cymbals rather than mallets. Walker also creatively disguises the meter of the piece by tricking the listener into thinking the downbeats are upbeats. Also included is an optional audio soundscape that not only provides a supporting sonic backdrop but interjects with additional manipulated sounds. Disguised comes as a professionally printed and bound score and includes individual parts in PDF format for printing or for tablet viewing.
