What You Will Learn

Become fluent in the fundamentals of music theory with the Grade 4 Music Theory course.

It's our belief that every musician needs to have the theory knowledge that supports their playing, singing, or composing skills. Designed to follow on directly from our Grade 3 Music Theory course, this course features clear explanations of music notation, many worked examples and practice exercises, definitions of important words and concepts, specimen questions and many helpful tips for students. As well as being suitable for candidates preparing for ABRSM music theory exams, this course also provides an excellent resource for anyone wishing to develop general music literacy skills. During the Grade 4 Music Theory course we'll cover...

  • Instruments of the Orchestra - Which instruments belong to which section? What are the transposing instruments? Which clefs do they use?
  • Double Sharps, Flats and Chromatic Scales - How do you write them? When do you need to use them? How do they all function correctly?
  • Primary Chords - What is meant by chord I, IV or V? How do you work out the notes in those chords? How do you know which key features which chord?
  • Breves, Ornaments and the Alto Clef - How do breves work? How do you read music in the alto clef? What does this ornament sound like and how do you recognise it?
  • Writing Music - How do you set rhythm to words? What makes a good answering phrase? How do you put music theory to good use?


Although as a child I learnt the piano I did not get taught theory. Thank you for making this so exciting and my 79+ year old brain work better. Thank you for this exciting journey.

Who Is This Course For?

All keen music students, performers and examination candidates.

Can you think of any other human endeavour where not knowing what you're doing is considered a positive? Understanding music theory is of great importance to all musicians. Music is a universal language and knowing how it all works is the key to improving. Our music theory courses cover all the essential elements of music from the ground up and are ideal for students preparing for examinations, as well as an excellent resource for anyone learning to read music. This course follows on from our Grade 3 Music Theory course.

Do any of these sound familiar?

"I'm applying for a music course and want to get a head start..."

"I'd like to read music and understand what's going on in a score..."

"I need more than just music theory definitions and terms, I want to know why theory works the way it does…"

"I'm looking to improve my performance skills..."

"I'd like to start writing music without an instrument…"


I look at all the piano players, and there are some quite good players. They all want to teach, one assumes so that they can earn, but there are few if any teachers among them. You are the only person I have found that I would call a 'teacher'.

Hi, I’m Gareth and I'm passionate about developing ‘the all round musician’.

Nearly 35 years of music examining with ABRSM, work with the BBC on Radio and TV, experience on the international concert platform, as a published composer and arranger, have brought rich resources to the 40 years of teaching in which I've engaged.

Scholarships at The Royal College of Music, Oxford University and St. Paul’s Cathedral gave me fantastic opportunities to learn from the best musicians, scholars and teachers. Working as Director of Music at Queen Elizabeth Grammar School then provided a wonderful opportunity to develop my teaching skills.

Teaching individuals and groups of all ages, and at all stages of development have refined a teaching approach that I hope is fun and engaging, and focused on explaining things clearly and logically. And that is what these courses are all about - understanding the basic principles with clarity, then going deeper, applying them to your musical life and liberating yourself as a musician.

It’s a rich and amazing journey, and I can’t wait for you to join me today!

Many students of music want or need to pass music theory exams and this course is very focused on enabling you to achieve that.

At the same time, theory is about much more than passing exams. Have you ever wondered what it would be like to get inside the mind of a composer? Think of a piece that you’re working on or listening to at the moment. What inspired the composer to write it? When did the composer live and what are the features of musical style at that time? Then what did the composer need to think about in order to compose the piece?

Theory explores the ingredients that bring music to life and, contrary to the idea held by some that theory kills creativity, it’s theory that enables musicians to make sense of their musical ideas.

If we go back in time music was in the world well before anyone dreamt up music theory. So do we really need theory? After all, we can all enjoy music without needing to understand the nuts and bolts. Some musicians have the ability to perform and improvise without completely understanding the theory behind what they are doing. I can manage a few words and phrases in Italian but because I understand more grammar and vocabulary in French I get on much more successfully in French than I do in Italian. Because I understand even more grammar and vocabulary in my native tongue I get on considerably better in English than I do in French. The more we understand of a language, the more fluent we become, and music is often described as a language.

The interesting thing is that music theory was taken very seriously as far back as the time of the Ancient Greeks, who were keen to explain how music worked and to establish why certain approaches were more successful than others. Ever since, theory has continuously evolved to keep pace with explaining musical development.

Having taught music for over 40 years, my experience is that the more students understand theory, the more they understand and appreciate the music they perform, and the more excited, creative and engaged they become.

Don’t learn theory for the sake of learning theory. Engage with music as a listener, a performer, and/ or as a composer then grasp the theory that will equip you to reach your full potential as a musician. That’s what makes music theory so exciting! Enjoy!
