What’s so bloody awful about the pedal harp? It’s a fantastic instrument. Yes, it makes sense to introduce the pedals at the first lesson. They are not such a big deal. As I said elsewhere, decide what kind of music you want to play. Given you have the opportunity to rent and learn pedal harp, why not do it? But if you really identify with a folk harp, get that. The same person can probably teach that, too.
