Even though researchers have documented the acoustic differences characteristic of the singer's voice, very less attention have been focused on examining the spectral characteristics across various registers in singers. Thus the present study aimed to document the spectral parameters, namely H1-H2, H1-A1, H1-A2 and H1- A3 in classical singers with the vidwath level of singing training across various registers of singing. Thus the voice was recorded from both singers and non singers on singing task and the recordings were analysed to extract spectral measures namely H1-H2, H1-A1, H1-A2 and H1- A3. The values of the H1-H2, H1-A1, H1-A2 and H1- A3 were further tabulated and statistically analysed using SPSS software. The results revealed that…show more content… Carnatic music has a very highly developed theoretical system. It is based upon a complex system of ragam (rag) and thalam (tal). These describe the intricacies of the melodic and rhythmic forms respectively. Carnatic music, mainly emphasizes on using the powerful voice with more prominence on using low-pitch and loud singing. Carnatic singing also emphasizes a precise shruthi or tonic pitch for singing with accurate breath pattern (Durga, 1997). Execution of long musical phrases/notes across different octaves, tempos, and clear articulation of vowels and consonants are crucial for Carnatic singing (Arunachalam, Boominathan, and Mahalingam, 2014). According to Radhakrisha and Scherer (2011), open-throated singing with forward placement of voice characterizes a good voice in Carnatic singers. Brown, Rothman & Sapienza (2000) reported that the presence of vibrato, singers formant and a lower jitter value among singers compared to that of non singers.Even though researchers have documented the acoustic differences characteristic of the singer's voice, very less attention have been focused on spectral characteristics of voice among Carnatic
