Trombonist, pianist

to share spotlight

It’s not always easy to share the spotlight, but Tuesday’s 11:30 a.m. concert at the Arizona Senior Academy features two stellar UA musicians who do just that. Their program features them alone and together in repertoire spanning more than 200 years.

Trombonist Moisés Paiewonsky, a prize-winning University of Arizona associate professor of music, returns to the ASA stage with pianist Elena Miraztchiyska, a UA doctoral candidate and concerto competition winner with whom he’s collaborated in the past.

The pair open and close the program with chamber music for trombone and piano.

To begin, they’ll offer a lyrical piece, and to end, a piece Paiewonsky calls “one of my favorites in the trombone solo literature,” Eric Ewazen’s Sonata for Trombone and Piano.

The Ewazen sonata is a modern work, written in 1998. While it looks back in time with an emphasis on classical forms, it fills these forms, Paiewonsky notes, with “modern harmonies and sonorities.” For example, he said, it puts “modality before tonality” and “color, texture and rhythm before melody.”

Miraztchiyska offers the Mozart Sonata for Piano in C Major, K. 330, a favorite of audiences (and of the great pianist Vladimir Horowitz). It is a classical-era piece, written some 200 years before the Ewazen. It’s one of Mozart’s loveliest sonatas, with an ebullient first movement, a deep and songful central movement and an energetic, buoyant finale.

“Perfectly crafted classical music in three movements,” said Paiewonsky.

Sustainability seminars start Wednesday

“Sustainability” is acting with the future in mind, so that others in the future can have the same opportunities we have today. In the desert Southwest that means capturing the sun’s free energy, saving money, reducing effects of climate change and using limited water carefully.

Academy Village’s annual Sustainability Seminars open with two seminars on Advances in Solar Energy Wednesday and Jan. 22 in the Great Hall of the Arizona Senior Academy.

Four seminars on Water Sustainability start on March 26. All seminars run from 2:30 to 4:30 p.m.

Wednesday’s first seminar includes two talks. The first features J. Roger Angel, the University of Arizona’s Regents Distinguished Professor of Optical Sciences and a highly acclaimed astronomer, inventor and designer of astronomical mirrors.

Angel is turning his work to solar energy, inventing new solar mirrors and lenses that concentrate solar energy more efficiently than current technologies, perhaps leading to a new generation of solar power technologies that create energy at costs similar to burning fossil fuels. He will present this new research — which has led to the development of a start-up company, REHnu — and also will discuss the overall status of solar energy research and development in Southern Arizona.

The second speaker on Wednesday’s program, Adria Brooks (UA department of physics), will move from the research frontiers and promise of Angel’s work to the performance of new and traditional photovoltaic (PV) technologies including rooftop systems commonly used to date.

The solar energy seminars continue Jan. 22 and will feature new developments for PV technologies and installations, including purchase compared to lease of residential systems, and discuss the emerging politics and policies that have already negatively affected use of PV systems and prospects for increased installation of solar power systems in sun-rich Arizona.

‘The New York Orphan Who Built Chicago’

Everyone knows Chicago’s iconic Water Tower, the sole architectural survivor of the devastating 1871 fire. Chicago rebuilt itself and by 1885 became the world’s early architectural leader in skyscrapers and then was nicknamed the White City, hosting the World’s 1893 Columbian Exposition.

If you look closer at the Chicago Water Tower, there is a plaque on its west base honoring DeWitt Clinton Cregier, a New York orphan from a family of 10 who became Chicago’s city engineer in 1879 and its 26th mayor in 1889.

Cregier was not only the impetus behind Chicago’s rebirth highlighted by the Columbian Exposition, but also was the hands-on engineer for new urban fire hydrant and water systems. Cregier also annexed land for Chicago, preparing for its future as America’s third-largest city.

Next Thursday at 3:30 p.m., the Arizona Senior Academy will host a talk by Cregier’s granddaughter, Gloria Cregier Emma, author of the 2011 biography of her grandfather, “The New York Orphan Who Built Chicago, The Story of DeWitt Clinton Cregier, a 19th-Century American Engineering Genius.”

Emma will present old photographs, official documents, newspaper clippings and drawings from her grandfather’s 40-plus years guiding Chicago’s growth in the late 19th century.

Cregier “was a humble man who did not seek recognition,” said Emma, adding that “Without his Golden Words in front of the U.S. Senate, Chicago would not have had the 1893 Columbian Exposition.”
