Voice in Spacetime
I used to sing.
I have a very light soprano voice (soprano leggero). Here you will find some pictures of my past performances.
[Click in the pictures to enlarge]
My first solo performance
Back in 1995, I started to sing as a soloist. Below are some pictures of my first solo performance, an aria of Bellini in the final Master Class section, at the Funrei Auditorium in Sao Joao del Rey City, Brazil, with Suzana Ferrari at the piano.
The Master Class was conducted by the great Brazilian soprano Niza de Castro Tank. Below is a picture of her and some students walking in the streets of Sao Joao del Rey. Notice the beautiful “mineiro”-baroque church in the background. Niza is the second from right to left, and I am the fourth from right to left.
In the picture below you will find me rehearsing an aria by Mozart, “Una Donna a quindici anni” during that same Master Class meeting.
Singing in the Choral
During several years, I was an integrant of the Madrigal Musicaviva of Sao Jose dos Campos, Brazil, once a very nice choral, with maestrina and pianist Nancy Bueno and tenor Lenine Santos as voice coach. (He was my private voice teacher for several years).
Below are some pictures of the Choral in 1995, singing Vivaldi’s Gloria in the Sao Dimas Church in Sao Jose dos Campos, Brazil. Can you find me?
Duet
I also sang in duets. Here are some pictures of me and contralto Eveline Stukenbrok singing the difficult piece by Pergolesi, Stabat Mater, at the Municipal Theater of Sao Jose dos Campos, Brazil, back in Oct., 1995. I am the one at left.
Joel Honorato, at the piano, did a nice job. Applauses for him too!
A challenging piece
Here is a very challenging piece: Rossini’s Missa Solemne. Below, some pictures of me as a soprano soloist of the Musicaviva Choral, in Nov. 1996. The performance was held at the Sao Benedito Church, in Sao Jose dos Campos, Brazil. You can find me (short haired) at the side of the soloist contralto Eveline (see previous section). The other soloists were Flavio Mesquita as bass and Lenine Santos as tenor.
In the more panoramic view below you can see Nancy Bueno at the piano.

And Nancy Bueno back as the maestrina of the Choral…
These are times that I miss. I have learned so much, not only good music and the art of overcoming stage fright, but also many aspects of my deep self that perhaps I would never know otherwise.

Christine, I’ve loved the pictures, the story and everything! It has sent me to the old times… Thanks.
Lets met, of course!
Kisses,
Lenine.

My sister sings. She told me that birds can be charmed by song. I have tested this and it works. Or maybe it has something to do with staring at a bird with your mouth open.
To do this, you have to repeatedly sing the same thing. I find that birds like songs with longer notes.

Hello Christine,
Here (http://egregium.wordpress.com/2007/12/) at your website is a link to my “peter schreier page”, a fanpage, which is obsolete.
Please change it in: http://www.mhalberstadt.net

Hi Marijke,
Thanks, I have just updated the link on my post where I mention him. A great tenor indeed!
Best,

Hi,
I have taken a few graduate courses in physics, studied some General Relativity and a little topology and Differential Geometry. I want to learn about Gauss’s Theorema Egregium. Can you recommend any books or links on this? Thanks,
-Toby

Hi Toby,
The first place that I have learned about Gauss’ Theorema Egregium was from this book, many years ago:
– M. V. Berry — Principles of Cosmology and Gravitation, Appendix B
It gives a nice outline. Another book at an easy level is this:
– Frank Morgan — Riemannian Geometry, A Beginner’s Guide, page 21
And moving on to more advanced books:
– Marcel Berger — A Panoramic View of Riemannian Geometry, chap. 3
– Richard S. Palais — A Modern Course on Curves and Surfaces, page 70
However, I am not a mathematician. Perhaps there are other references with deeper developments that I am not aware of.
Best,
Christine

Hi Christine,
Thank you very much, I am going to look into all those books and probably buy one. I want to develop a deeper understanding of not only General Relativity but topology and geometry. This theorem by Gauss sounds very fundamental and deep and I really want to learn it. Thanks for the info, looking forward to looking into it,
-Toby
