A katcheri is an assembly of musicians and audience in the context of Carnatic music or Karnatick music. It is presented in the concert format. The music fraternity of connoisseurs and common people assemble at the katcheri venues to listen to classical music concerts of vidwans. Etymologically the word "katcheri" is derived from Urdu language and in Hindi to mean a court of law.
Vocalist Ariyakudi Ramanuja Iyengar (1890–1967) established the modern katcheri (concert) traditions in Carnatic music. Among the women artists, M.L. Vasanthakumari and D.K. Pattammal pioneered the promotion of kutcheri culture. Among the most notable woman vocalist the first woman artist to be receive the highest civilian award of Bharat Ratna in 1998 was M. S. Subbulakshmi (1916–2004); she had started her career in music with her first katcheri when she was 15 years old which was then a big hit among the audience and music critics.
