During the past five years this writer has worked with over 200 trumpet players ranging in ability from the total beginner to the advanced high school musician. She has found the concept of tonguing to be one of the most difficult for students to comprehend. While working with these students she discovered that incorrect tonguing can lead to poor tone quality, bad intonation, and pitch inaccuracy. These in turn lead to over-all poor performance and discouragement for student and teacher. The purpose of this paper is to discuss various methodologies of teaching correct tonguing procedures and their effectiveness in application. The topics to be included are: initial attack, importance of breath support, legato tonguing, staccato tonguing, rapid tonguing, double tonguing, and triple tonguing.
