LENOX — For its second summer season, the Tanglewood Learning Institute is taking to heart lessons learned from high-intensity launch by offering a streamlined schedule of about 75 ticketed events in 2020, down from 140 in its first summer season.

That's the message from TLI director Sue Elliott, who organizes the cross-cultural, multidisciplinary program based at the Boston Symphony Orchestra's four-building, year-round Linde Center for Music and Learning, which opened in June.

"We have an idea of what worked well last summer and what we wanted to change," she told The Eagle.

What's not changing is the mission of what Elliott calls "a grand experiment" — an interactive experience for patrons to mingle with musicians and other artists on the verdant Tanglewood grounds and in Cindy's Cafe, part of the Linde Center.

The schedule for the June 21-Aug. 23 TLI season is designed to offer "dynamic, leading edge programming to inspire curiosity and foster a deeper experience of Tanglewood concerts and classical music, while exploring ideas resonant with the wider culture," according to a BSO announcement released Thursday.

The goal reflects "a cultural landscape that values active engagement and learning through experiences that dissolve the traditional barrier between performers and audiences."

To that end, many events are designed to complement the concerts by the BSO, smaller ensembles at Ozawa Hall and by the advanced young musicians of the Tanglewood Music Center's summer institute. Last summer's TLI slate attracted about 14,000 patrons, nearly one-third of them new to Tanglewood and the orchestra.

There will be three Immersion Weekends, the TLI's flagship attractions, down from four last summer, in sync with the BSO's schedule based on key anniversaries and Tanglewood traditions through talks, films, open rehearsals, master classes, outside-the-box performances, and visual arts programs:

BEETHOVEN WEEKEND

(JULY 17-19)

This three-day immersion marks the 250th anniversary of the composer's birth, accompanying the BSO's cycle of all five piano concertos with soloist Paul Lewis, the BSO's Koussevitzky Artist for the season. Exploring the inspirations and influences driving the creative process, the events include a talk on "Beethoven's Music and the Emerging Viennese Popular Style" by Erica Buurman of San Jose State University and editor of The Beethoven Journal who will discuss how the music of the Viennese ballroom held a long fascination for Beethoven; "Decoding Beethoven's Sketches," led by violinist Nicholas Kitchen and featuring the Borromeo String Quartet; and "Dear Ludwig ," a combined TLI Talk and Boston Symphony Orchestra prelude concert that explores musical responses to Beethoven's work.

VIOLINIST ISAAC STERN @100

(JULY 24-26)

This weekend celebrates the centennial of his birth, complementing BSO programs featuring leading violinists Augustin Hadelich, Midori, Pamela Frank and Joshua Bell performing music Stern championed during his six-decade career that included his leadership that helped save New York's Carnegie Hall from demolition. Sessions include a leadership in the arts panel discussion with BSO President and CEO Mark Volpe and others, an open rehearsal of the Boston Symphony Orchestra, and a TLI-TMC Open Studio piano trio master class led by Emanuel Ax and Yo-Yo Ma.

FILM WEEKEND

(AUG. 14-16)

One of the TLI's most popular attractions last summer, returns in 2020 to accompany John Williams' 20th annual Film Night, Aug. 15. The institute's explorations of music as a key element of cinema include "Film Music Comes to the Concert Hall" with Tufts University associate professor of music and director of undergraduate studies Frank Lehman, which focuses on Williams' concert arrangements and delves into how film scores can be transformed into stand-alone concert hall presentations.
