£26Solfege & Oriental Solfege: Quarter Note - Rast, Bayet, Siga, Kord, Hijaz, Ajam, Nahawand - Major & Minor Scales
Trusted teacher: With over 8 years of experience as a Solfege, Oriental Solfege, Oud, and Oriental singing teacher, I am a Lebanese musician currently residing in Mönchengladbach, Germany. I honed my skills for 8 years at the Lebanese National Conservatory. Prior to my relocation, I taught at Casa Beethoven Academy in Lebanon and also held private music lessons. As a concertmaster, I performed with the oriental orchestra "Loubnan Assalam" for over 5 years. My move to Germany was motivated by my pursuit of graduate studies at the University of Kamp-Lintfort. Fluent in English, Couramment en français, ولغتي الأم هي اللغة العربية. Aber leider spreche Ich ein bisschen Deutsch. Solfege, the foundation of music theory, is an essential tool for any musician who wishes to understand and create music. It provides a way to identify and communicate notes, intervals, and rhythms, and it is the key to developing musical literacy. In this class, you will delve into the world of scales, exploring the unique characteristics of Western and Oriental scales. We will study the following scales: Rast, Bayet, Siga, Kord, Hijaz, Ajam, Nahawand- Major & Minor Scales. In addition to these Western and Oriental scales, we will also introduce you to the quarter note, which is not traditionally found in Western music. It is a quarter note with a unique and distinct sound. Whether you are a beginner or an experienced musician, this class will provide you with the knowledge you need to use scales effectively for improvisation, singing, and playing any instrument. With this knowledge, you will be able to: * Read and write music (dictation) in solfège notation for both Western and Oriental scales. * Identify and communicate notes accurately in the context of various musical traditions. * Develop a deeper understanding of music theory and rhythmic concepts. * Infuse your musical performances with a broader range of expressive possibilities. We will use the book "المقامات الشرقية by Georges Farah" as the main reference for our study of Oriental solfège. This book is considered the best book in the Middle East to teach Oriental Solfège. Discover the power of solfège to enhance your musical skills and open up a world of new possibilities!

IELTS Coach | Tailored Exam Preparation | General English (Peckham)
Dean
Our first lesson with Dean was productive and an eye-opener. The lesson made me realize there are a few critical areas that I needed to grasp and understand to articulate the IELTS exam preparation. The lesson was fun, and Dean is a good attention detail tutor; he takes time to give a clear explanation of what to focus on. His energy is amicable, and he takes his work seriously. Thank you for the first lesson, and we look forward to our following lessons.

Arabic language and teaching Arabic to non-native speakers, foreigners and beginners. (Riyadh)
Hiyam
We are absolute beginners and Mrs. Hiyam made it super easy for us to dive in the lessons and in just 3 lessons we learned half of the alphabet and pronounciation. Now I can read most of the signs in the street. We will continue learning with her. We are new in Riyadh and she was so kind to come to our house to teach us. She is very sweet and smart! You will not regret any minute with her .
