Early Release Note

The author, specialists at the Center for Learning & Teaching (American University in Cairo), and members of the Rebus Community have decided to launch this open series ahead of its full completion. We want to equip you with a quality open resource for teaching and learning by which you can successfully adjust to circumstances arising from the current COVID-19 health crisis and resultant physical distancing protocols.

We strive to complete the first edition of the series in the coming weeks to months. As a result, you can expect to see the following updates (to be recorded in the Version History):

• Additional play-along duets (until each unit contains approximately fifteen total). If you would like to submit your play-along scores to be considered for inclusion in the series, please read the Statement about Score Submission on the Rebus Community platform.
• Additional Appendix items such as: the Keep Going Scores (compiled PDF of all the exercises and compositions in the series, in order of units); the Obelisks (compiled PDF of all the commissioned compositions in the series, in order of composer); and MP3s of all play-along MIDIs.
• Additional hyperlinks to other open sources throughout the series.
