The minimum instruments needed for the Level 1 are included in the starter kit.
You could also purchase a frame drum (10-14” is good), a crystal singing bowl and a wind gong.
If you decide to continue on to a Level 2 course with us, you would want to purchase additional bowls to be able to create sound intervals, and also tuning forks if you decide to also include those in your practice.
Can you let me know at what stage this will be needed and can you also recommend any suppliers for the instruments which are not included in the starter kit?
You would need the minimum instruments when you start the foundation course so that you can do the exercises. The additional instruments can be added as you wish. You are required to have more instruments for Level 2. If you need additional help finding suppliers please see this FAQ or email us at email@example.com.
