Terms & Conditions

‘You’ refers to anybody using the services provided by JAK Vocals, both the voice students, and those who book lessons on behalf of and/or have parental responsibility for the students.

‘Me’ and ‘I’ refer to Jasmin Keshavarzi, who is providing vocal tuition under the business name of Jasmin Keshavarzi.


I promise to:

  • be on time and fully present for your lesson 

  • keep up to date and work continually to improve my knowledge of voice science, evidence-based practice and vocal pedagogy, in order to provide you with the best teaching possible

  • honour your vocal goals

  • provide a safe, kind and supportive in which to learn

  • treat all people with respect, regardless of race, gender identity, sexual orientation, religion, ethnicity, disability, or national origin, both inside and outside the teaching studio

My expectations are for you to:

  • seek clarification when you don’t fully understand a concept, exercise or technique

  • practice what we cover in lessons, as consistently and mindfully as you can, so that you can make progress towards your goals

  • treat all people with respect, regardless of race, gender identity, sexual orientation, religion, ethnicity, disability, or national origin, both inside and outside of lessons

Please remember, you are investing in a skill that will serve you for your lifetime. Not only will singing and using your spoken voice efficiently bring you great joy, but there are also many other benefits.

Learning with JAK Vocals, I aim for you to feel heard and supported as you learn, and to have fun during your lessons. There will be a focus, as much as is beneficial in each lesson, on developing knowledge and understanding of how the voice works, in theory and in practice, so that you feel empowered to make healthy and creative vocal choices for the rest of your life, as well as obtaining the functional ability to perform them.


  • It is assumed you have the appropriate technology to carry out your voice lessons online before booking - you are responsible for your ability to connect

  • Please arrive or log in no earlier or later than 5 minutes before your lesson time. 

  • If you are running late or experience technical difficulties connecting, please notify me as soon as possible by text (+44 (0) 7958 290 891)

  • If you are late for the start of your lesson, the lesson will still finish at the scheduled time

  • In the event of a ‘no-show’ I will text or email after 10 minutes to check everything is ok if I haven’t heard from you, and the lesson will be cancelled after 15 minutes and no refund will be offered


All lessons are to be booked online via Once a booking has been made, an invoice will be sent within 24 hours and this is expected to be paid before the lesson. Payments are to be made via credit/debit card through square or via Paypal. Very rarely, bank transfer payments will be accepted if the other options are not available.

If payment is not received, I reserve the right to cancel the lesson. Late payment of invoices will incur an admin fee of £15 and services will be postponed until payment is made in full.


You are free to reschedule or cancel your lesson up to 48 hours before the start time of the lesson.  Lessons cancelled within 24-48 hours will be charged at 50% and lessons cancelled within 24 hours of the scheduled lesson times will be charged in full. You have the option of rescheduling lessons up until that point.

Refunds may take up to 10 working days to arrive back in your bank account.


In the case of illness, it is important to note that there are plenty of ways to make a lesson productive without a lot of singing: repertoire selection, sight-singing and rhythm-reading practice, theory, musicianship, listening and learning from other artists, aural skills, and over zoom we don’t have to worry about spreading germs.

So please take this into consideration and only cancel your lesson if you’re feeling really unwell. 

Of course, in the case of emergency, I will offer refunds or a reschedule for cancellation within 24 hours, but not for colds and coughs. 

If your voice is fatigued from misuse or overuse, it is important to attend your lesson, as we will do exercises to alleviate the issue and make a plan for recovery and maintaining your vocal health.


Your lesson fees go beyond the scope of your 1:1 lesson. So that I can serve you to the best of my ability, I spend many hours outside of lesson times:

  • on professional development activities such as attending workshops, additional training and courses,

  • on further independent study and reading around vocal science and pedagogy topics, such as studying for an MA in Voice Pedagogy

  • researching repertoire

  • lesson planning

  • investing in studio resources and equipment - technology, sound equipment, singing aids, books and sheet music to loan

  • reviewing audio and video of student performances and providing feedback

  • frequently communicating and liaising with other internationally renowned voice teachers and West End professionals for advice, strategies, development and education
