Most beginning students do very well to start on 30-45 minute weekly lessons. After just a few lessons, students can expect to know basic rhythms, notes and tunes - I tend to immerse them in music from the get go!
If practice time is limited or you are a more advanced student (grade 4 and above), 60 minutes is recommended. Of course it's ultimately down to your budget.
- 30 minutes: £17
- 45 minutes: £24
- 60 minutes: £30
