Shorty was the first to define his music as "Soca" during 1975 when his hit song "Endless Vibrations" caused musical waves on radio stations and at parties and clubs - not just in his native Trinidad and Tobago, but also in cities like New York, Toronto and London. Soca was originally spelled Sokah, which stood for the "Soul of Calypso" with the "kah" part being taken from the first letter in the Sanskrit alphabet, representing the power of movement as well as the East Indian rhythmic influence that helped to inspire the new beat. Shorty stated in a number of interviews that the idea for the new Soca beat originated with the fusion of Calypso with East Indian rhythms that he used in his 1972 hit "Indrani". Soca solidified its position as the popular new beat adopted by most Trinidadian Calypso musicians by the time Shorty recorded his crossover hit "Endless Vibrations" in 1974.
