Tacettin Tınaz “Keyboard of Oud” is not an oud method. However, most of the oud methods are missing or not explained and shown in sufficient detail; The sound system of Turkish music, the tuning of the oud, the position of the frets on the keyboard according to the makams (including 1, 3, 4, 5 voice transposes) are the main topics of this book. The tools named “Transpose Table for Oud” and “Transpose Wheels” developed by the author and presented to music lovers with this book for the first time in Turkey and in the world, are of a quality that will enable both the comprehension of the transpose subject and the ease of this process. The videos presented as an appendix to the book will make the subjects easy to grasp. The book is more visual than textual. All images are in color. The colors in the images are not randomly used, but coded (matched) with concepts and terms. Coded colors will make it easier for the reader to grasp and perceive. “The Keyboard of Oud” can be used as a supplementary book by those who teach and learn to play the oud.
