The Key of C Major for Beginners
Welcome to the first lesson in our beginner course on the key of C Major. In this lesson we delve into fundamental music theory focusing on the C Major scale and the chords that we can create using the notes of the scale.
The C Major Scale
The C Major scale is an ideal starting point for beginners as it contains all white keys making it easy to visualise the notes on the piano. We start by outlining the correct fingering to ensure smooth transitions as we move up and down the scale. We also emphasise the importance of a natural wrist position whilst playing scales on the piano.
The Numerical Approach To Scales
Transitioning from traditional note names to a numerical understanding of scales offers a more versatile and functional framework for analysing jazz harmony. This approach involves viewing the scale as a series of numbers rather than letters. The numeric system simplifies the process of building chords, chord progressions, and understanding the relationships of the chords within a particular song or key.
C Major Diatonic 7th Chords
From each degree of the C Major scale we construct triads and then extend these triads to create seventh chords which adds a richer sound compared to basic triad voicings.
7th chords are a foundational component of jazz harmony and pave the way for exploring more complex chord progressions and voicings.
Practice Tips
-
Warm up with the C Major Scale: Focus on correct fingering and maintaining a natural wrist position when moving up and down the scale. Practice the C Major scale over 1 octave, and then 2 octaves.
-
Think Numerically: In jazz, we visualise scales numerically which helps to analyse chords, chord progressions, and jazz standards. For each major scale, think 1-2-3-4-5-6-7 instead of the note names.
-
7th Chord Drills: Learn the diatonic 7th chords in the key of C Major and complete the drills in chapters 4 and 5 to help you visualise the notes of each 7th chord split between 2 hands.
- Apply The Theory: In the upcoming lessons of this course we use these concepts to play "Moon River" & "Fly Me To The Moon" - spend 50% of your practice time on the theory drills, and 50% playing jazz standards.

Damn it
Hi Hayden,
On chapters 4 and 5 (the drills), you end up playing the root and 5th on LH with fingers 3 and 1, respectively, and the 3rd and 7th on RH with fingers 1 and 4, respectively. I understand that once we start playing the tune there is fluidity on this as can be shown in chapter 6.
BUT, since the drills are important as you emphasize, is your finger configuration here the suggested one based on your experience. I say this because i naturally went for fingers 5 and 1 (LH) and 1 and 5 (RH) since the fingers in-between them correspond exactly to the 3 keys in-between the notes being played.
Hi Nivaldo,
Firstly please excuse my late reply – I’m just catching up on comments after a busy weekend.
This is a great question.
The fingering I use here is somewhat different to when playing a jazz standard. To be honest I didn’t really think about the fingering I was using, but my goal was to try to clearly show the notes of the 7th chord being shared between both hands. If I was to use LH 5-1 and RH 1-5 it might make it a little harder to see what I’m playing as my hands and fingers would be covering all of the keys.
So the short answer is that I chose this fingering to make it easy to visualise the notes being split between both hands.

As you will see in the graphic that I shared in the forum thread earlier today – also attached to this comment – I wrote the fingerings as as 5-2 for every left hand chord in Moon River.
The reason is that in later lessons, we often develop the left hand further by playing the 7th, the 9th, or the 10th with our left hand thumb. For this reason we want to keep our thumb ‘available’ which is why I wouldn’t play my left hand as 5-1 (pinky and thumb) because then the left hand is far less ‘mobile’ and ‘adaptable’ as the left hand fingers cannot overlap the thumb.
However, if we look at another one of our beginner tunes, such as “In A Sentimental Mood” – pianogroove.com/jazz-piano-lessons/sentimental-mood-for-beginners/ (watch from around 4:50).
You will see that I voice the triad in my left hand with my 4th finger on the bottom and my thumb on the top, this is because we are adding a descending ‘minor line cliché’ which is very common device to play over minor chords.
The point I’m trying to make here is that the fingering very much depends on the harmonic context, what is happening in the melody, what chord is coming next and what chord came before.
There is no ‘set-in-stone’ fingering in jazz piano and as you correctly highlight we have a certain degree of fluidity and flexibility.

What I’m demonstrating in this lesson is simply a drill to help you visualise the notes of a 7th chord spread between both hands. The fingering is in some ways irrelevant because there is no harmonic context and no melody note or melodic context.
So in short, I wouldn’t get too hung up on the fingering, and instead focus on learning lots of new jazz standards.
Once you get 15 or 20 jazz standard under your belt, I guarantee that your fingering will be much more intuitive and almost ‘2nd nature’.
I hope that helps Nivaldo and let me know if you have any further questions.
Best,
Hayden
Thanks for all this info Hayden!
When I started practicing the first 8 bars for Moon River this morning I switched my LH to use fingers 5-2 based on your graph from your fingering email reply. I had the suspicion that you did that to allow a greater role for the LH later or something like that…and from your response now I see I was not off the mark. So…already busy practicing the 5-2 on LH.
Just one additional comment here: according to the PDF, in bars 1-2, your LH descends from Cmaj7 to Am7 but in the video your left hand ASCENDS from Cmaj7 to Am7. I like the sound of the latter better but wanted to ask you if there is a reason for this difference…
Thanks!
Nivaldo
My pleasure, Nivaldo.
I believe in the next lessons on this song (found in the same module) I show that the left hand can be played in different registers, ie. we can move the left hand down one octave which creates a ‘stronger’ foundation.
Playing the left hand further down the piano will often open up more options, for example in this lesson which is “2.4” in this course – pianogroove.com/jazz-piano-lessons/moon-river-extended-voicings/ – you will see that I introduce some chord extensions into the A-7 voicing, and the left hand root and 5th must be voiced an octave down for this to work.
My recommendation would be to study all of the lessons in this module and the voicing variations that I demonstrate.
Always remember that anything you see written in 2-staff notation (transcriptions) is simply one possible way to play the song and voice the chords.
When playing jazz piano our goal is to play spontaneously. By studying my video lessons and demonstrations it will help you to see and visualise chord voicing options on the actual piano keyboard, and not needing to rely on written notation.
Anyhow, please work through the rest of the lessons in this module and my explanations and demonstrations should answer your question in more detail.
If I can help further just let me know and enjoy the lessons!
Cheers,
Hayden
