Jazz music invokes an ambiance of "cool," and most live jazz performances represent that coolness. Many live jazz performances take place in dark, richly decorated night clubs that use low ambient lighting to add to the mood. Live jazz performances can sometimes have a nostalgic or vintage ambiance.
Jazz musicians are widely appreciated for their talent and passion, and their music is appreciated for its immense emotion and soul. Live jazz performances are generally animated and full of feeling, even if the music is slow.
Jazz musicians are often known to improvise on stage during live performances, creating music at the spur of the moment with their band mates. Live jazz performances often include "jam" sessions that can last anywhere from 30 seconds to over 15 minutes.
