Thanks for the offer to send the CD. But, let me search a little yet: Is it a commercial CD?
Thanks also for the Bernstein citation.
Onomatopoeia shows the ability of a composer to transcribe sounds. If one writes only music, then it might have been overheard, or be a transcription of "folk music". In such a case, it's not very original because the sounds transcribed were heard as musical notes. Transcribing sounds into musical notes requires a higher level of transcriptional abilities. So, the scores of composers who can do this well merit a higher level of respect in performance. It's a consideration in trying to determine which came first: the "folk music" or "performance tradition" or the composer's score.
