What To Expect


The Tritone Expo will present nearly 70 music-related companies, artists, and non-profits from the St. Louis area spread out over 40,000 square feet of exhibition space on two floors.


Both floors will feature interactive exhibits allowing you to fully experience a wide variety of locally made musical instruments, amplifiers, and effects, as well as unique educational activities.

Kids' Activities

Upstairs there will be multiple rooms geared directly towards activities for children, in addition to an entire expo that was purposefully designed to be fun and exciting for the whole family.


The Expo will feature recording workshops, beat-making stations, two instrument petting zoos, on-the-spot bands comprised of attendees, group music lessons, and online video lesson exhibitors.

Art & Photography

A gallery devoted to music-related art, video, and photography where you can talk with local artists and photographers, and check out their amazing work. (And, buy prints, too!)

Food & Entertainment

During lunch, food trucks will be parked outside in the beautiful Cortex Commons and all-day you can get your fix for coffee, food, and live music inside at Park Avenue Coffee.

More Than Your Average Guitar Show

The Tritone Expo Offers Fun For The Whole Family

The 2016 Tritone Expo truly has something for everyone — bring the whole family and make a day (or a whole weekend) of it! Our location is easily accessible from all major St. Louis highways and offers three gigantic free parking lots and plentiful street parking. And, the surrounding area has so much, as well — the new IKEA, plenty of restaurants and shops, and of course, Forest Park! Get directions!

I was blown away, simply put. I have attended many guitar shows over the years including Arlington, Nashville, and Winter NAMM. The foot traffic was as good if not better than the regional shows and, at times, the NAMM show as well.

There was a great spirit of community and enthusiasm for this field of interest. I was struck by the world-class level of quality work that is coming out of this town. The attendance was overwhelming, too. I can only imagine this growing and growing.

My expectations for the show had been to meet new people and let them see my work, if I sold anything it was just going to be icing on the cake. The cake was iced as one gentleman who took an OM guitar into the hall to try came back and bought it.

The Expo Is The Accelerator

The Tritone Expo's Mission Rests On Four Main Pillars


To foster local St. Louis businesses, as well as those from the surrounding region, that are simultaneously pushing the envelope for what is possible, and collectively bringing a renewed sense of craftsmanship, to the music industry.


To promote St. Louis as a hub for music education, which it has been steeped in for decades, not just at the university level with top rated programs that produce working musicians and engineers, but also at the start, with a wide-range of exceptional programs for children and beginners.


To create and promote a marketplace that elevates sales for local and regional businesses that are producing world-class musical instruments by hand, as well as our other sponsors and partners that share our intense passion for music.


To create a community of artisans that can share knowledge and resources in order to strengthen and promote the local music economy, as well as, challenge and encourage each other to be more innovative.
