While created primarily out of improvisation, Aaron Locklear’s In the Fog explores mathematically deduced rhythmic patterns, as well as the use of intervallic symmetry within a tonal context. This collaboration of improvisatory and mathematical material creates a sophisticated inner structure housed within a tuneful casing of accessible listening. This is a contemporary gem for the modern percussion duet. Written for marimba and vibraphone, Locklear also incorporates the use of celeste during certain passages (glockenspiel may be substituted for celeste). This extra color brings extra life to an already vibrant composition. This piece comes as a professionally printed and bound score and includes individual parts in PDF format for printing or for tablet viewing.
