Study Overview

Brief Summary

The researcher will contact the music schools in and around Dakshina Kannada district India and will inform the music teachers regarding the purpose of the study. The researcher will collect the personal details of the intermediate singing students who have completed the junior grade examination willing to participate in the study.  Those selected students who are trained carnatic singers will be contacted personally via phone call to explain the purpose and procedure of the study. During this call the researcher will also inquire about the participants willingness to participate in the study. The study will commence only after obtaining written consent from the participant.

A baseline evaluation will be performed before an intervention program. The two groups of singers will be instructed to refrain from performing any vocal exercises or their regular vocal routine before the baseline evaluation to ensure their natural voice and laryngeal structure are accurately represented. The effect of confounding variables will be controlled by instructing them not to consume spicy food, caffeine alcohol tobacco and drink less than 6-7 glasses of water daily.

Following the baseline assessment participants in the experimental group will be undergo structured warm-up regimen (vocal and non-vocal) which has been compiled in the module. These warm-up regimen will be conducted at their music institution under the guidance of the researcher for 12 consecutive days before formal singing training begins. The researcher will implement the intervention by grouping the participants into sets of two. The participants will be instructed to perform the exercises only under the guidance of the researcher to maintain consistency and minimize practice effects. Each intervention session will last approximately 30 minutes. Participants who do not complete 12 days of intervention will be eliminated from the study.
