Isepp's intervention of 1940 is documented by a single photograph taken towards the end of his cleaning of the painting.
The varnish applied in 1940 was thin and only slightly discoloured; it was easily removed during the recent cleaning, as was Isepp's retouching, executed in watercolour.
Someone once told me that Martin Isepp was the only man to whom Britten ever entrusted the preparation of his operas, and when I asked him if that was true, in a Q and A session at Ravinia, he truly blushed and was almost unable to continue speaking, perhaps because he knew it was true and those productions and experiences had been so special to him.
Isepp only once, at least in my hearing, but in the act of coaching, in every class or lesson I ever heard from him, are the two largest gifts to my life as a vocal coach.
As I indicated above, I remember Martin Isepp only once making a thorough explanation and, through the duo he was coaching, demonstration of consonant-to-vowel ratios, the use of which brings not only good diction, but more vocally beautiful, onomatopoetic vowel tone to all forms and styles in German language singing.
In Example 1 from "Nacht und Traume," I have endeavored to indicate where singers, most often start and stop consonants, rather similar, I am sure, to what Martin Isepp found in that wonderful class.
Isepp dared his young baritone to experiment with consonants starting quite sooner than most of us in the room thought possible or even attractive.
She studied voice with Barbara Doscher and Joan Jacobowsky, and coached with Gerhard Husch, Martin Katz, Martin Isepp
, Dalton Baldwin, and Gerard Souzay.
