About Me
Jawa (1996) a Syrian oud player. I was born in Aleppo, and I grew up in Damascus, Syria. I started playing music at the age of eleven. I chose the Oud as my instrument because my father used to play it everyday at home when I was young. Gradually, I fell in love with it and now I feel an unlimited feeling of freedom while playing it. When I was six, I started ballet dance lessons.

At the age of eleven I had to join music classes in order to reach a higher level of ballet dancing. I studied music at Sulhi Al Wadi music institute In Damascus and after one year of studying music, the Oud became my passion.

I decided to study music and six years later, I graduated at the same music school as where I have started.

In 2012 I went to Egypt with my family, and there I continued my music study at “Beit El Oud” the Arabic Oud House institute under the supervision of the Iraqi Oud player Naseer Shamma.

In 2014 I went to Istanbul to receive private lessons by the Turkish oud player Nacati Celik.

Since June 2015, I have been based in the Netherlands.

In the Netherlands, I got to know great Dutch and international musicians whom I had the chance to perform with and who allowed me to learn more and enrich my knowledge about music.

I specialize in teaching about Music and how to play the Guitar.
In class, I always make an effort to understand what are the goals and interests of all students, as well as their skills. This way we can address the issues at hand more effectively and make sure the student never loses his/her interest and focus in music and his/her instrument. I believe that an honest and friendly relationship between teacher and student is essential for this exchange of ideas to happen more clearly and fluently, so I do my best to make everyone feel comfortable enough to share their thoughts freely.
I offer good and personalized classes. This means that there will be special care with your interest in music and guitar, all basic skills will be worked upon and strengthened, all specific requests and ideas will be addressed, both improvisation and interpretation can be developed, and exploring potential, achieving goals and having fun are main priorities.
Come and enjoy learning more about Music and Guitar!

Hi there! My name is Norica. I am a pianist and a piano teacher from Tokyo.

Just quickly to the point: My approach is holistic and systematic. It uses lots of fun exercises and nice educational materials from Japan in addition to the Internationally recognized standard books. (Don't worry, you don't have to understand Japanese!) You learn not only how to play piano but also how music works- music theory.

I know what my students are good at and not so good at right off the bat. That's why I can tailor the lesson plans to their goals and needs.

Also, if you like to take an ABRSM exam, the syllables will be tailored accordingly. So what will be tested on the day of the exam is integrated into the lessons and my class/lesson offers all-round preparation for the exam. I have helped my students pass G1, 3, 5 and 6 with a good score.

Another important aspect of my lesson is to focus on improving cognitive skills - increasing memory, right-hand-left-hand-coordination, sustained attention, nonverbal communication, and a feeling of independence and freedom.

I do so with unique materials from Japan and fun training.

Currently students from 4 to 76 years old are taking my lessons. As an educator, I am committed to the process of learning while making lessons enjoyable and constructive.

Please drop me a line if you're interested. If you have any questions about the lesson, feel free to ask.

I will be happy to answer all your questions!

Thank you

Have you wanted to learn to play the piano for some time or do you want to teach your child to play the piano? My name is Faye, and play the piano since the age of 6 years old.

My name is Daniil. I am a pianist and composer from Ukraine. I obtained my Bachelor's degree in composition, piano, and pedagogy at Moscow Tchaikovsky Conservatory in 2018 and my Master's in Music composition from the Royal Conservatory of The Hague in 2020.

The main power of music is in its ability to open up worlds of communication that are inaccessible otherwise. Therefore, in our lessons, we will use technical exercises, solfège, and music theory (if/when needed) to achieve the level of performance that will allow for the ultimate goal – having fun playing for or with your friends and family. Apart from working on your favorite pieces and classical repertoire, we will work on your skills of sight-reading and improvisation. We will also play pieces together, either on a piano in four hands or with me on the violin.

I have almost ten years of experience teaching piano, composition, solfège, harmony and counterpoint, and music theory. Among my students were kids aiming for (and succeeding at) admission into higher music education institutions, conservatory students who needed help with their music theory and piano classes, and kids and adults who studied music in their spare time.

No matter what your goal (or lack thereof) is for studying music, we will find an appropriate pace, structure, and repertoire. The classes can take place either at my house in Scheveningen or at a student's location in The Hague.

Whether you are a music enthusiast who would love to play your favourite songs on the piano, an experienced musician looking to take the next step into your expressiveness and confidence when playing, or a student who needs to learn or reinforce music theory, you are in the right place!

I'm Irene Martínez, a pianist and recent graduate of the Master of Music program at Codarts University of the Arts, and I would love for you to be my next student. I have previous experience teaching piano at different levels to people of many ages (children, teenagers, and adults), because I'm passionate about sharing my love of music and I believe that, with the right approach, everyone can be capable of expressing themselves through music.

As a pianist, I have performed solo concerts of classical music, and also being part of ensembles, from chamber music to contemporary and other genres. I adapt my lessons and approach to the student's particular needs, so:

- If you are already a pianist with some experience who wants to develop certain technical aspects and delve much deeper into musical expression...
- If you are a beginner, or someone who wants to pick up playing again after a long time...
- If you are interested in learning music theory in a much more efficient and fun way, relating everything you learn to your favourite music...
- Either you want to prepare an entrance exam to pursue music in a professional way; or you want to keep it as a hobby...

...my lessons are definitely for you!

I speak fluent Spanish, English, and French; so if you want to have lessons in one of these languages, don't hesitate to contact me! :)

Istanbul Lute (Lavta) & Oud Lessons – Greek & Ottoman Music

Hi! My name is Kyriakos, I'm 29 years old and I'm a musician and teacher. I studied at Codarts University of the Arts and my main focus is on Greek traditional music and Classical Ottoman music.

I offer lessons in Instanbul lute (Lavta) and oud, for all levels — from complete beginners to more advanced players.

During the lessons, we can work on things like:
Maqam Theory
repertoire from both Greek and Turkish traditions
Technique and playing
Improvisation
Music theory
Reading and understanding sheet music

My teaching approach:
I try to adapt the lessons to each student. Everyone learns in a different way, so I try to find an approach that feels natural and enjoyable for you, rather than simply following the same method with everyone.

I'm a patient and positive person, and I want the lessons to be a relaxed space where you can learn, ask questions and enjoy playing music.

Lessons can take place at my place or at your home, depending on what works best for you.

Whether you are just starting out, already play an instrument, or simply want to explore Greek or Ottoman music, feel free to send me a message. I'd be happy to hear what you are looking for and see how I can help.

Moreover, if you are interested in this repertoire and you play another istryment, I can also teach the style and the specific ornamentation of it.


Everyone is welcome, including complete beginners!

Learning and playing string instruments can be incredibly fun and fulfilling, but it is not an easy process, and it requires discipline, structure and proper guidance. I offer an experience tailored to each student's specific needs and learning style, and I focus in depth on a variety of topics that I consider to be fundamental to achieving a high level of performance and interpretation on violin and viola; such as basic music theory, music history, a well-rounded and versatile technique, and collaborative music-making.
My lessons are suitable for beginners and advanced students of all ages. I rely on a variety of teaching materials; some that are intended for children, others that are made for adult learners, pedagogues and performers.
I consider myself to be a rather involved teacher; I am attentive, I am available for resolving issues and clarifying doubts outside of lesson time, I help students with instrument procurement and maintenance, and my homework and instructions are clear and easy to follow.
