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 from different tremolo techniques. Record and played back video in slow speed. Time data was analyzed. Interval times were computed, turned in to Descriptive Continuity (DC) and compared. Interview was made on fingering order, tremolo principle, practicing procedure, playing cautions, and tremolo-free stroke comparison. Moreover, guitar virtuosos were also studied. There are many practice procedures such as staccato practice, 3-finger practice, variable speed practice or accent practice. While staccato practice may reduce gap on specific fingers, accent practice may result in smooth 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 can try pima and pimi instead of pami. Tremolo finger movement is similar to 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.
