THIS BOOK IS NOT FOR SALE! This book presents unfinished music compositions for solo piano composed by Claude Ziad El-Bayeh. He was not a composer nor a musician and did not study music since he concentrated on his career as a professional engineer and researcher. It was just a hobby he enjoyed doing in his rare spare time that helped him relax and remove his stress. Therefore, do not expect high-quality compositions, especially the music was written on Guitar Pro 4, 5, and 6 software, which are not the best in the market, and they lack many musical annotations for piano and other instruments. The main reason for publishing this book was only to save his work on the internet and in the form of a hard copy with the hope of learning music and correcting the pieces in the future. Electronic devices, especially laptops and computers, are not reliable for saving information since the software or the electronic circuits might be damaged at any time, and all your hard work can disappear suddenly without any prior notice. The music pieces in this book are presented as follows: 1. Piano Concerto 1-Mvt 2 Op.49-B (Arranged for Piano) 2. Piano Solo 1_Op.1 3. Piano Solo 3_Op.4 4. Piano Solo 13_Op.22 5.
