Zomverera zomwe zili pamwamba pa ntchito ya chida zimalemba malo a zala mbali ziwiri - zopingasa ndi zowongoka. Sunthani zala mopingasa kuti musinthe kamvekedwe ka mawu, ndi kusuntha molunjika kuti musinthe mawu. Kukanikiza mphamvu kumasintha voliyumu. Malo ogwirira ntchito ndi osalala. gulu lililonse la makiyi asonyezedwa mu mtundu wosiyana. Mutha kuyisewera m'manja awiri komanso ndi zala zosiyanasiyana, zomwe zimakulolani kusewera nyimbo zingapo nthawi imodzi. Continuum imagwira ntchito pamawu amodzi ndi 16 mawu a polyphony.

Cholemba chilichonse chinali ndi zilembo zakezake. Amagwiritsidwanso ntchito ngati zida zankhondo kubisa mauthenga.

Kenako kunabwera telharmonium, yomwe kale inkagwiritsidwa ntchito poimba nyimbo basi. Chida ichi, chokwera komanso cholemera matani 200, sichinali chodziwika kwambiri pakati pa oimba. Phokosoli linapangidwa pogwiritsa ntchito majenereta apadera a DC omwe amazungulira pa liwiro losiyana. Ankapangidwanso ndi zokuzira mawu m’nyanga kapena kuulutsidwa pamizere ya telefoni.

Pafupifupi nthawi yomweyo, chida chapadera choimbira choralcello chimawonekera. Mawu ake anali ngati mawu akumwamba. Inali yaying'ono kwambiri kuposa yomwe idakhazikitsidwa kale, koma idakhalabe yayikulu poyerekeza ndi nyimbo zamakono. Chidacho chinali ndi makiyibodi awiri. Kumbali imodzi, phokosolo linapangidwa pogwiritsa ntchito dynamos yozungulira ndipo inkafanana ndi phokoso la chiwalo. Kumbali ina, chifukwa cha mphamvu zamagetsi, makina a piyano adatsegulidwa. M’chenicheni, “mawu akumwamba” panthaŵi imodzi anaphatikiza kuyimba kwa zida ziŵiri, limba lamagetsi ndi piyano. Choralcello chinali chida choyamba choyimbira chamagetsi chopezeka pamalonda.
