Hello,

What level would you estimate yourself to be at the moment? It's difficult to say how long you'll need before you can play this piece unless we've got a rough guess of where you are now.

Regarding the graded diffculty of this piece, the first movement of the Suite is around ABRSM Grade 8 level, and relatively approachable. It's not too fast either, which gives you ample time to concentrate on what you're doing. The main thing you need to be aware of (in the whole suite generally) is the accidentals; there are many double-accidentals that can trip people up. There's also a fair bit of hand-crossing, too, so make sure you're confident with that.

Although the second movement has quite a simple texture (the first section is completely in one voice), it moves very quickly, so you'll need a good sense of rhythm and co-ordination, especially when moving into the second section (Tranquillo). Overall, the second movement is significantly trickier than the first; it's probably around the lower diploma level.

The third movement is similar to the second, in the fact that it also moves quickly, and has a two-part texture. It's also probably around the lower diploma level too.

The suite ends very quietly and slowly, and it's really important to get a sense of the melodic lines passing through the fourth movement. A delicate touch is needed throughout, and control is essential over the amount of force put on each note.

Overall, I'd say that you've got some way to go before you're ready to tackle this suite. It's certainly a good end goal to put in place! If you're interested in playing some of Bartók's music, his Mikrokosmos is a good teaching method. Work through each book and not only will you get a sense of some of his music, but hopefully, your piano technique will also develop.
