Ragtime is usually defined as a song that is in 2/4 time or 4/4 time people usually get it confused with 3/4 time however that is considered a ragtime waltz. Ragtime is used by taking the base line and using progressive harmonic chords that may be punch or silent while the melody is carried out through the Alto,Soprano lines as it uses syncopation which makes the song being played off beat and unexpected.
