Solo Guitar - Level 5 - Digital Download SKU: A0.1243643 By Brad Rau. By Brad Rau. 20th Century. Individual part. 6 pages. Brad Rau #838597. Published by Brad Rau (A0.1243643). This piece was composed by Brad Rau for solo guitar. Rau has always been fascinated with dark, evil, sounding music, and this is his attempt to write some that are truly dark. This is also inspired when Rau has a kidney rupture that eventually causes him to have it removed. This was recorded on Brad's third album, In a Very Unusual Manner. The main theme is based on two minor chords a tritone apart. It then accelerates in tempo into an octatonic excitement with constant time signature changes that jar the listener. Then the main theme comes back, this time in Tremolo. It ends with the same solo theme it begins with. The piece is inspired by works of Erik Satie, Invocation and Dance by Joaquin Rodrigo, and the Usher Waltz by Nikita Koshkin.
