If you're in The Hague, I'll give you a lesson in subcontrabass
playing (bring an oxygen mask and a brown paper bag!). Either that, or
you can 'pretend' to be interested in studying at the Royal
Conservatoire, and get a free lesson at Open Day or by appointment. We
have Rien de Reede and Emily Beynon, among others.... This would
probably work in Amsterdam as well, but they have Harrie Starreveld.

Cheers, Domsk
