The "disco sound" was much more costly to produce than many of the other popular music genres from the 1970s. Unlike the simpler, four-piece-band sound of funk, soul music of the late 1960s, or the small jazz organ trios, disco music often included a large band, with several chordal instruments (guitar, keyboards, synthesizer), several drum or percussion instruments (drumkit, Latin percussion, electronic drums), a horn section, a string orchestra, and a variety of "classical" solo instruments (for example, flute, piccolo, and so on).
