The development of the Scat singing exercises in Jazz music

บทคัดย่อ

This creativity research is based on the qualitative method which aims to
(1) study knowledge of scat singing and to create scat singing exercises in
jazz music, and (2) evaluate student learning outcomes from the scat singing
exercises. This study employed the research and development method.
Research tools included structured interviews, index of item objective
congruence (IOC), and achievement evaluation forms. Data providers were four
jazz vocalists and jazz vocal instructors. The data collected were analyzed using
the content analysis approach and presented in an essay format. The results
revealed that steps for successfully practicing scat singing, consist of listening,
syllable selection, song selection and rehearsal planning. The development of
the scat singing exercises in jazz music found that the content of the exercises
was divided into three difficulty levels: easy (1), medium (2), and difficult
(3) and created in the form of video files, which were under the concept of jazz
theory. The harmony included ii-V-I patterns, dominant seventh chords, and
ascending and descending chromatic. The melody included non-harmonic tones
(upper and lower neighboring tones), harmonic tones, tension notes, and
enclosures. The rhythms included eighth notes, triplets, and quarter notes.
There are twenty exercises and three levels of difficulty. The effective scat
singing practice relies on having basic musical skills, especially those involving
listening and imitating examples. The results of the scat singing evaluation from
the target group of 20 participants, all first-year undergraduate students aged
18 or older majoring in jazz music, indicated a high level. The average score
of knowledge and understanding was 4.19 with a standard deviation of 0.45
(M = 4.19, SD = 0.45). The average score of application was 4.30 with
a standard deviation of 0.53 (M = 4.30, SD = 0.53).
