Yes, it gets harder. All the time. eg.
For the new ” ALL MY RHAPSODIES ” for Alto and ( Brahms ) Orchestra :
1. I will use my own five Corcoran texts. ( See below )
2. I will watch Brahms´s tessituras ; eg. he approaches a top of E flat / E by a composer´s stealth. – The low Brahms limit is around A or A Flat But I´ll need a dark, erotico, rough-pressed approach to her absolutely lowest F. ( ” Well, is this , then, death ? ” )
How ?
