First, pedagogical and scientific definitions of an effective vibrato will be compared, and various waveforms will be electronically synthesized for aural evaluation. Then, many (n &gt; 10) college-level players will be audio- and video-recorded. These audio tracks, as well as excerpts taken from available professional recordings, will be digitally analyzed; the video footage will then be used to motivate biomechanical explanations for aural differences among players. These investigations will hopefully result in a refined definition of an effective vibrato, ultimately streamlining teaching methods.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Katherine Hagen with Kathleen Horvath (Music) and Gary Chottiner<a href=\"\/physics-senior-projects\/files\/2009\/05\/KatherinHagenPoster.ppt\">Analysis of Violin and Viola Vibrato Waveforms<\/a><\/p>\n<p align=\"justify\">\u00a0Vibrato is a series of expressive pitch oscillations produced by left hand movements on the violin and viola.
