Many people feel that hearing sneezing sounds when we start work. During the marriage, there will be many people and while the Muhurtham is being performed a sneezing sound is considered a bad omen. If the music is played the sound of music may make us not hear sneezing sound. That is why these are arranged. This is what I heard from some people.
Any of these music concerts will be good for the people attending the marriage to have a good time pass.
