TOC – The Open Choir

TOC – The Open Choir in the Hornsey Town Hall as part of the Crouch End Festival June 2017

Hear us Singing 

 The Open Choir does not require an audition. 

We welcome singers from all tribes and traditions. Because this is an improvisation project you need some experience as a singer ( in a choir, band, solo, teaching or vocal workshops) to take part. There may be some preparation sessions for people who want to join who have little improvisation experience.

Join Up!

TOC fifth season starts September 2017. 

Our concert is coming up on November 12th 2017. 

TOC Day Intensives
12.30 – 18.30 – with a shared lunch at around 2.30pm.
Day Intensive Info: 
Building on the great progress TOC has made since beginning in March 2016 this is a chance to get down to some more in depth work using the fun techniques Jenni has been evolving for rehearsing, including the exploration of transpirations – a notion Jenni is exploring whereby one is learning and developing skills through collaborating musically with more experienced vocalists, including Jenni or members of her team from the professional choir TIC. A transpiration is like the process of osmosis or in biology where the plant drinks the water and then returns droplets to the air through its leaves. This is a process of intuitive exchange and deep listening. There will be also be rehearing in choir formation and plenty of time for small group practice – and a focus on solos and duets often growing out of transpirational practice. 

Introduction to TOC

This is an improvisation choir, for singers with some experience. We will be working towards informal friends and family concerts.

We will be creating improvised vocal music together, both in the moment of the performance and through devising processes in rehearsals. Jenni Roditi will lead through directed conducting and by giving musical instructions on which we will build new pieces.
Some sessions will include rehearsal assistants from TIC or other outside special guest leaders from time to time.

The Mission

The mission is to work with people who have some experience in vocal performance or who are willing to develop their improvisation skills. The conducting signals method  focuses and shapes what is latent. The latent process in the group determines the shape of the conducting signals. It is a two way street. Within this melting pot a key aim will be to perform exciting and unusual vocal pieces created in the moment – as well as devise pieces, develop ensemble skills and enable singers to grow creatively while learning to respond to direction, rather like an actor and a theatre director would work together. We are working towards public performance so we need to aim for the best we can.

Important qualities

As well as bringing your enthusiasm to TOC you will be open to working with others and be willing to try something new. You may or may not feel able to step forward and take a solo role in certain moments. Your abilities and openness will be taken into account in the directing process. It is important that you are happy to take on a variety of roles within the choir; flexibility being a core skill. You will be willing to take musical direction from Jenni and participate in creating music established through directed conducting.


We will have self-selecting and spot-check processes for tuning. If you are wondering about your tuning skills you can let us know. If we spot that your tuning may need work we will let you know. Those people with a query on their tuning may be offered some time together to work on improvement in small groups or privately before the rehearsals start. There will be a small fee for this tuition.


We reserve the right to ask people to leave if they are being disruptive or we feel they are not able to fully support the challenge the TOC project entails.

Being redirected: Vocal Tai Chi is Jenni’s other voice project and here you can attend workshops, or occasionally work privately with Jenni on most aspects of your musicianship. This may be an option for those who cannot meet the challenge of this project. There are other avenues that may also be suggested to help you, including a new musicology research project to be based at the a leading conservatoire, looking at people who are so called ‘tone deaf’.

Vocal Tai Chi sessions can be booked by joining or through messaging Jenni Roditi .
