The atonal singback “melodies” are significantly longer than the melodic ones, make zero musical sense and seem impossible to memorize after hearing them played just once. They’re so overwhelming and long.
Seems to be a very ambitiuos and prestigious choir that even can afford to filter its singers on a regular basis. Out of curiosity: Which atonal pieces did you actually sing with this choir?
Go gradually through the move to atonality in music history and listen to lots at each stage,
like becoming immaculate with all intervals
The variations are endless but really, just pick a small set of exercises you can do consistently and slowly upgrade the difficulty.
