Music can be defined as Mind’s Ultimate Silence In Contemplation. Thoughts regarding past happenings and future plans are merged and surrendered in the present to the strains of music (vocal or instrumental). Sonic waves ranging from 20Hz to 20,000 Hz vibrate the ear drums of human beings and animals. Noise is also composed of sonic waves but arranged in erratic combinations creating nuisance to the hearer.
Music is composed of 22 notes of standard vibrations. These notes are separated by silence. A judicial combination of notes and silence result in soothing music to the ears. A mixture of sustained note, passage from one note to another and silence is called composition of a tune. The lyricist writes phrases with meanings matching a sequence and also fall in the rules of metering. This comprises the song.
Indian music is made up of a term called “RAAGA”. Raaga is nothing but a set of musical notes in the ascending or descending order of frequencies. Classical Indian music adheres to strict set of musical notes in systematic rhythm. A day of 24 hours is divided into 12 equal parts of 2 hours each and it is customary to sing or play stipulated raagas during those specified timings.
Music in films or sung during semi-classical concerts allow additions of rare grace notes. Indian music in films should catalyze communication between the film director and the audience so as to serve the purpose of conveying the full meaning of the video by the audio. For example, a scene comprising of a dark place purports a temple with the background sound of bells and instruments like sitar and flute. The same dark scene kindles the imagination of the audience to think of a graveyard or a haunted house, if the background score is composed of stormy winds.
