What this genre is not?

• The standard repertoire in a traditional mode of presentation
• Most musical comedies and operettas.
• Menotti [save for possibly The Unicorn, The Gorgon & The Manticore], Argento [save for possibly Postcard from Morocco] and other standards of the academic canon.
• Pieces that that don't place an equal value on the text [even if abstracted, performative or non verbal] as on the music.
• Pieces that value entertainment over taking an audience on a journey.
