Less harmonic rich pieces

What are some less harmonic rich Chopin pieces?

I’m adapting some Mazurkas for modern hurdy gurdy. Many mazurka themes work well as a folk dances. But it’s much harder to adapt whole piece, as hurdy gurdy is bound by its drone strings. Hence I’m looking for pieces with little modulation. What works in terms of modulating is going to dominant or subdominant. Everything else is quite harder.

If you’d like to hear if it makes any sense I can post some snippets. Also listen to Winterreise adapted similar way by Matthias Loibner and Natasha Mirkovic.
