The practice of lulling a child to sleep through music must be about the oldest tradition imaginable. All parents have wanted their children to sleep at some point, if only to have a little peace and quiet — and to plot strategies for getting their own shuteye.

Pianist Alessio Bax knows all about sleep — and lack thereof. He's a first-time parent, and his 22-month-old daughter Mila is, like any child that age, a handful, not to mention impossibly cute.

In 1970, a young business school grad — and failed opera singer — named David Gockley landed a job as business manager of the Houston Grand Opera. After two years, at age 27, he moved up to general director.

Over the next 30 years, Gockley transformed the company into a hothouse for new and revived American opera. During his tenure in Houston, Gockley presented 35 world premieres, including John Adams' Nixon in China, Stewart Wallace's Harvey Milk, Leonard Bernstein's A Quiet Place, Mark Adamo's Little Women and three operas by Carlisle Floyd.

Barry Douglas knows a few things about handing down traditions. In this Tiny Desk performance, he passes along the musical heritage of his Irish homeland in the form of old Celtic songs he's arranged for solo piano.

When the New York City Opera (NYCO) announced its final performances and imminent bankruptcy in September 2013, opera lovers, not just in Manhattan, were shocked.

The Estonians are serious about singing. The power of human voices practically propelled the small Baltic country to independence during the Soviet era. In the late 1980s, hundreds of thousands of Estonians routinely gathered to perform forbidden patriotic songs. The events energized the nation, leading to what was called the "Singing Revolution."

Violinist Lara St. John has attitude in spades. It's in the sound of her playing and in the arc of her career.

The Chicago new-music ensemble Eighth Blackbird is on a roll. Just after winning its fourth Grammy in February, the group received a MacArthur Award for Creative and Effective Institutions; the prize came with a $400,000 grant. Hand Eye — Eighth Blackbird's second album in seven months — just came out, and this season the group marks its 20th anniversary. The celebration includes an extensive tour, with world premieres of music by Bryce Dessner and David T.

Late in 1968, it was astounding to me how one of the best-loved bands could create one of the least-liked songs. It was "Revolution 9," near the end of The Beatles' sprawling White Album.

But then, I was only 7 years old and, frankly, those eight minutes of chaotic sounds and mumbled words were positively frightening. And who was that guy who kept intoning "number nine?"

One hundred years ago, a musician was born who took the world by storm, both with his violin and with his warmhearted humanity. Yehudi Menuhin was born April 22, 1916, in the Bronx to Russian immigrants. He began his career as an astounding child prodigy in velvet knee pants. But two men who knew him well — documentary filmmaker Bruno Monsaingeon and violinist Daniel Hope — maintain that as Menuhin grew older, he turned out to be far more than just another virtuoso.

With his long beard, homemade horned helmet, flowing cloak and spear, he was known as the Viking of Sixth Avenue. He was born Louis Thomas Hardin in Marysville, Kan. in 1916 and later called himself Moondog. At 16, he was blinded while fiddling with a blasting cap.

Ane Brun recently turned 40, and she — like many of us who've reached that milestone — has been taking stock of her life. It's a life filled with music and success, but there have also been a few rough spots. Like the time we scheduled her to play a Tiny Desk concert in 2012 and she was forced to cancel an entire North American tour (with Peter Gabriel) due to a lupus flareup. Brun, a Norwegian native based in Sweden, was diagnosed with the autoimmune disease when she was 27.

Prolific and multifaceted British composer and conductor Peter Maxwell Davies died Monday at age 81 at his home in the Orkney Islands, off the northern coast of Scotland. His death, from leukemia, was reported on the websites of both his publisher and his management company.

The harpsichord was eclipsed first by the fortepiano in the 18th century and eventually by the modern grand, but that doesn't mean the instrument is out of sight or out of mind.

You might call it old wine in new bottles, but what sweet, masterfully crafted wine it is. Upheld by Stillness, the debut album by the young and vibrant British a cappella choir ORA, presents a contemporary twist on a 16th-century classic.

Opera singer Lawrence Brownlee is known for portraying kings and princes. But lately he's been thinking about real people: Trayvon Martin, Michael Brown and Freddie Gray, to name a few.
