This year's Make Music NY fest is back and imminent. The 10th edition of the unorthodox city-wide celebration of music goes down Tuesday, June 21, and it has also expanded to cities all across the US and Europe, having started, as it turns out, in France.

As usual, NYC plays host to a ton of special events throughout the day. Here are some highlights:

Glass on Water: Two performances of Phillip Glass's Etudes on at Pier i (West 70th and Riverside Park) beginning at 5 PM. Glass himself will take part in the first performance, which features 42 middle and high-school aged performers.

Mass Appeal: Like past years, you can show up and take part in large-scale instrumental performances — like pianos on Cornelia Street or music boxes in Transmitter Park — not to mention accordions, bagpipes, boomwhackers, cymbals, modular synth orchestras, and much more.

Guitars in Times Square: Stop by Times Square for a guitar lesson from teacers from the NYC guitar school (or, if you're lucky, the naked cowboy).

Uptown Funk and an Exquisite Corpse: Harlem will play host to a number of funk and jazz shows at a wide range of community clubs.

Street Studios: "Starting at 11am on June 21, seven small mobile recording studios will appear on sidewalks throughout NYC. These “Street Studios,” coordinated by Make Music New York and Found Sound Nation, will engage passersby and MMNY festival musicians in the spontaneous, collaborative production of original music."

Inside the Bird Chorus: The Brooklyn Botanic Gardens (as well as 4 other locations) will play host to performances that celebrate avian life and are conceived as dialogues between improvising musicians and bird calls.

Concerto For Buildings: A street in SoHo will be shut down for eight "Musical Buildings."

Governors Island was host to a few MMNY-related this past weekend: Porch Stomp on Saturday and Punk Island on Sunday.

There are also free shows happening at Joe's Pub, Madison Square Park, the Highline park and more. Check out the full schedule here.
