Today we will work on the second exposition of our invention. We are in the new key that you modulated to yesterday. Begin by stating the original subject in the new key in the opposite voice from exposition 1. This happens exactly as the last cadence occurs, so there is no loss of musical momentum. The other voice rests during this time. Next, transfer the subject to the other voice, transpose by an octave, and create counterpoint to work with this statement. Continue this second exposition by writing a sequence that uses motivic elements from your subject. The length of this should be a model, copy, and half copy. The goal of this sequence is to modulate. If your original subject was in a major key you are headed to vi, and if your subject was in a minor key you are headed to v. After the sequence add two to three measures in the new key based off of motivic elements presented in your subject. End with a strong cadence in the new key. See the attached diagram for more details on the invention. This is all we’ll do for today. Consult your theory textbook or a colleague if you need more information about inventions. Thanks to both Carlos and Xavier for suggesting this project.
Join our Bradley Composition community in Final Bar Line Frenzy this summer. Our goal is to collectively reach 100 final bar lines (completed pieces) this summer! Once you complete a composition, comment on this post. Tell us the title, instrumentation, and provide a link to the piece if possible. Also include the number out of 100 in your comment to help us track our progress. For example, the first person to comment on the post would add 1/100, the second person would add 2/100, etc. What constitutes a completed piece for Final Bar Line Frenzy? It can be an original composition, an arrangement, a transcription, a fixed media piece, a project created in a DAW, a multimedia project, a multi movement piece, or a collection of short pieces. Use your discretion, but think of this as a completed piece that is of a quality that you would be happy to present in composition lessons, is ready for performance, and would be ready to send off to a publisher or feature on au...
