1. An electronic musical instrument comprising:
- manipulation means including an at least two dimensional continuous surface manipulation region, and a positioning element operative proximate said continuous surface of said manipulation region for achieving performance manipulation within said manipulation region;
means for detecting time based serial position data coordinates on the basis of serial positioning of the performance manipulation of said positioning element within said manipulation region;
means for detecting directional change and for conversion of data pertaining to a determination of the geometric coordinate locus of the performance manipulation, on the basis of a predetermined number of time based, serially detected position data coordinates; and
a tone signal generation circuit for performing effect control on musical tones based on the detected position and directional change and conversion data from said means for detecting and said manipulation means.

Abstract
An electronic musical instrument includes a tone generator, a manipulator for defining a manipulation region and for performing manipulation within the manipulation region. The manipulator has a first detector which detects serial position data on the basis of positions of performance manipulation within the manipulation region, and a second detector which generates changing-degree data of a locus which is constituted by the serial position data. The tone generator generates musical tone with effect in accordance with the changing-degree data to thereby impart various effect such as vibrato with ease.
