Landis Maitland-Whitelaw-On the Guadalquivir
On the Guadalquivir was originally written for voice and guitar. This adaptation is for unaccompanied clarinet. It depicts a river in Spain and starts out with a pastoral section reflecting on the feeling of being beside this river and then breaks into melodic chorus/verse sections. You can hear a representation of it here on SoundCloud. 

The notation for this piece is available to purchase at $2.00 / page.
