Le petit rien by François Couperin arr. Snell
This abridged version of Le Petit Rien by F. Couperin is from Essential Piano Repertorire, Level 3, published by Neil A. Kjos (2006).
Couperin's keyboard music is published in 4 Books, each book subdivided into 6 Ordres. An ordre being a handful of pieces, each imaginatively titled, for example: Les Dominos, Le Rossignol en amour and Le Tic-Toc-Choc.
Le Petit Rien is the last of the 7 pieces that make up the 14th Ordre, so in Book 3.
The original piece is a rondeau: a refrain and 2 episodes (couplets). So A B A C A.
If you would like to look at the original score, it is here (p.254).
The Clown and the Ballerina by Ben Crosland
The Clown and the Ballerina is published by Editions Musicum Ferrum.
Badlands by Christine Donkin
Badlands are areas that are very dry, heavily eroded and barren. They exist all over the world including Alberta, Canada which Christine Donkin visited as a child. One unusual feature of the Alberta badlands are the hoodoos, huge, perhaps 6m high, sandstone pillars formed over millions of years.

It may be helpful to have an image of Badlands in our head whilst we play this piece. This might help us give character to our playing.
This piece is in ABA form and makes use of the Dorian mode.

Polonaise in G Minor by J. S. Bach
This Polonaise in G minor, BWV Anh. 119 is RCM (2015) Level 3.
It is one of several Polonaises from the Notenbüchlein für Anna Magdalena Bach (1725), notated it is thought, in Anna Magdalena's hand. Perhaps she wrote it?
A Polonaise is a dance, originally from Poland but popular in France during the 17th-century, hence the name. It is in triple time and has this underlying rhythmic feel:

Dance of the Gypsies by Martha Mier
Dance of the Gypsies is from Signature Solos book 3 (Alfred).
I think this is one of those pieces that can work at a variety of speeds, it could certainly go a little faster than I play it here. Choose the speed that works for you.
