Band And Orchestra

Currently on hold due to Covid

Horizons K-8 hosts a fee-based instrumental music program offered by Sullivan and Sullivan Music.

If your student even wanted to learn to play a musical instrument, here is their chance! This is a wonderful opportunity for talents to come to life and be discovered. More importantly, music provides young people with a means of purposeful recreation that can be a lifelong value.

Band classes are taught by Denny and Gaylene Sullivan. Denny and Gaylene are retired Jefferson County School teachers, having spent 30 years in music instruction. Denny is a string and brass specialist, and Gaylene is a woodwind specialist.

Classes are offered for these traditional band instruments:

Clarinet, flute, sax, trumpet, French horn, euphonium, trombone, tuba, concert percussion

Classes are 45 minutes long and held FRIDAYS after school this year in Spanish/music room. Both are involved in every class. Your student receives the advantage of two teachers and individual help.

There will be a class for Beginning Band (1:00-1:45), a class for Advanced Band (1:45-2:30), a class for Beginning Strings (2:30-3:15), and a class for Advanced Strings (3:15 – 4:00). No experience is needed for the Beginning Classes. Advanced Classes require one full year of previous band or string classes. Registration fees for each session are below.

There are three sessions offered during the school year: Fall: September 7 – December 7 (no class on October 22), – 10 Classes, $160

Winter and Spring Schedule to be announced later. For more information please contact Denny Sullivan

The choir information will be updated shortly.

Horizons K-8 offers choir through the Sullivan and Sullivan Music fee-based program. In its fifth year at Horizons, Choir is a wonderful opportunity for kids to grow musically, meet new friends who share their love for singing, and to learn HOW to sing! All levels are welcome.

The Horizons Choir is taught by Alice Hartman.  She has taught the choir for many years and enjoys being part of music at Horizons in many different facets. She has had some wonderful opportunities with the choir in the past, such as singing with the original “Peanuts” jazz band at Macky Auditorium, singing the National Anthem at CU Basketball games, and making regular visits to sing at Frasier Meadows Retirement Home next door. She looks forward to more great things in the year ahead!

Our schedule mirrors the Sullivan & Sullivan Music schedule. There are 3 sessions each year, Fall & Winter & Spring, at a cost of $160 per session. The Fall Session this year runs from September 7th to December 7th, with no classes on October 22nd. The Winter and Spring schedules will be announced at a later time. Classes are 45 minutes long.

If you are interested in being a part of a Horizons Choir, please contact Alice Hartman at

We look forward to adding new voices to our wonderful singers!

Peace Jam

PeaceJam is an international service and leadership organization that has its roots in Denver. Horizons has had an active chapter since 2004.  PeaceJam works to bring the lessons of Nobel Peace Prize winners to young people through student developed service projects, curricular lessons and leadership conferences.  At Horizons we have a 5th-8th grade PeaceJam club that meets weekly during lunch. Students discuss issues that are important to them, identify needs in the Horizons, local, national and global communities they want to help and then develop service projects to help meet the need to serve and education the broader community. Some projects this group has completed in the past include: Trick or Treat for UNICEF, the Oxfam Hunger Banquet, bicycle and school supply drives for Somali refugees in Boulder as well as numerous family movie night and bake sale fundraisers for Boulder Flood Relief, Hurricane Katrina and Sandy Relief, the Oceanic Preservation Society, and the Haiti Relief Fund. Our 6th-8th grade club members can participate in two leadership conferences – one in the fall (the Slam) and 8th graders are eligible to participate in the spring conference (the Jam) in which they spend the weekend learning directly from a laureate. For our younger students during Making a Difference A&S, Junior PeaceJammer classes are offered. In these classes we focus on studying one Nobel Peace Prize Laureate and their lessons on making a difference in the world.



Allies club is focused on creating a community of acceptance in school. We spread anti-bullying messages and encourage people to stand up for those in the minority. An ally is someone who does not necessarily identify as LGBT, but supports this community by standing against bullying and harassment. Allies can be straight or cisgendered, or they can identify as LGBT. Anyone can be an ally!


At the February 2016 Council Meeting the Horizons Garden Project was unveiled. It is amazing to see the collaboration come to fruition. Please stop by the garden to see what we have growing, ask a student for a tour, they have become amazing stewards of our garden.

Please check back for volunteer opportunities.
