Choose how to take part
Two ways to join. Same concert. Same certificate. Same animated artwork.
Workshop · HK$2,480
Build it with us, in person. A three-hour facilitated session — children sand, fit, string, and paint their ukulele alongside our instructor. Walk out with a finished instrument, a Van Gogh Sites Foundation certificate, two concert tickets, audition eligibility, full guided lessons, and the come-alive AR experience.
Home Kit · HK$1,780
Build it at home, on your schedule. The full kit ships to your door with guided video instructions for every step. Includes the Van Gogh Sites Foundation certificate, two concert tickets, audition eligibility, full guided lessons, and the come-alive AR experience — same ending, your own pace.
Bring a friend and save over HK$900!
Two participants booking the Individual workshop together each save 20% on their ticket, and we will include a third concert ticket for a guest to share between you. The friend can be from any school. They just need to attend the workshop with your child.
How it works: two parents book Individual workshop sets together, both children pay HK$1,984 instead of HK$2,480 each, a third concert ticket is included for the pair to share, and children attend the same workshop session and perform together at the concert.

ChordSpheres guides you step-by-step through creating your own animated AR version of your painted Starry Night ukulele.

The audition selects 20 participants for the featured stage performance. Those selected take the stage and receive an additional certificate from the Vienna Boys Choir Music Academy Foundation in
recognition of their performance.
Every other participant joins the audience ensemble segment, playing their painted ukulele together from the audience. It's one shared concert — everyone plays, everyone is part of the performance.
No one sits it out.
