Suddenly, trees are flowering, the grass is greener, and mornings are filled with the sweet noise of chirping birds. Hitting the streets for a bit of entertainment becomes that much more exciting, but when it comes to outdoor fun, the May sunshine can sometimes feel like the only perk without a price tag. Thankfully, Boston has plenty of free spring events to fill our days. From fresh air sketching sessions to moments for mindfulness, here are this week’s free events around Greater Boston.

DOWNTOWN CELEBRATIONS For those who celebrated Cinco De Mayo last weekend with margaritas and tequila, and want to keep the party going without the repercussions of cocktails, the Downtown Boston Alliance and Boston’s Consulate General of Mexico will be holding a cultural party in Downtown Crossing. Expected to showcase traditional Mexican folk music as well as various artisan goods, the event allows attendees to stop by during lunch hour to immerse themselves in the historical and cultural background of the holiday. May 5, noon-2 p.m. 1 Franklin St. downtownboston.org

PICASSO FOR A DAY If you view detailed sketches in utter awe, wondering how people produce landscapes and portraits with pencil strokes, you’re not alone. The Seaport organizes sketching classes for both budding artists and experienced drawers. This Tuesday, the class will be taught by Boston-based artist Lee SOEMS. DJ Real P spins a set to get the creativity flowing. May 6, 5-7 p.m. 131 Seaport Blvd. bostonseaport.xyz

SING YOUR PRIDE When Molly Knight, a New England Conservatory soprano, was awarded a 2024 Entrepreneurial Musicianship grant, she set out to create “Gay as a Songbird,” selected programming that elevates queer voices within classical music. This Thursday, Knight’s curatorial efforts will culminate with a gala, featuring a celebratory showcase of music by notable queer musicians and composers — from Roan to Poulenc. May 7, 7 p.m. NEC, Burnes Hall, 290 Huntington Ave. necmusic.edu
