Sound continuity comparison study of nine tremolo methods in Francisco Tarrega s Recuerdos De La Alhambra

Abstract

This is statistical approach to guitar performing study with objective to compare continuity of tremolo by analyzing time data from different tremolo techniques. Using video camera to record and play back in slow speed, time data of each striking finger was analyzed. Interval time between one stroke to another were computed and turned in to Descriptive Continuity (DC). Results were compared in each method. Sample guitarists were interviewed about how they play tremolo, what fingering order they use, what tremolo principle they have, practicing procedure, cautions while playing, and comparison between their tremolo and free stroke. Moreover, guitar virtuosos were also studied. Good tremolo can be achieved from different practicing procedure. Practice procedure such as staccato practice, 3-finger practice, variable speed practice or accent practice may work well for guitarist. While staccato practice may reduce gap for student with too much gap on specific fingers, accent practice may result in smooth and balance sound. Trying to play a couple of fingers at the same time may improve tremolo continuity. Thinking that tremolo is arpeggio on the same string is a good psychological principle. Guitarists are encouraged to choose their best fingering order, not only pami fingering order is good, but others such as pima and pimi, are also good. Tremolo is free stroke with hand angle perpendicular to strings. From this study, the minimum cycle speed of professional guitarist is 140 rpm, and, for general guitarist is 122 rpm.
