Visualize the G major scale layout on the keyboard
The layout of the G major scale is six consecutive white keys followed by one black key (F-sharp) right before the final note at the top of the scale. If you were to think of the scale as a shape, or terrain, it would be a flat surface with a single bump (the one black key) on the top right one note before the end.

This is what the G major piano scale looks like on the staff for both hands together in a single octave ascending and descending:
Play the G major scale with hands alone
When you’re learning to play the G major scale on the piano, approaching the scale with your hands separately is a good place to start. In order to picture the pattern of the scale and the order of the fingering clearly, it’s important to know the core positions of the scale.
Core positions are groupings of notes and fingers that divide the scale into two distinct patterns. The core positions of a scale always consist of one group of 3 notes, played with fingers 1-2-3 (shown in red on the chart), and one group of four notes, played with fingers 1-2-3-4 (shown in blue on the chart). In the case of the G major scale, the top G of the scale in the right hand and the bottom G of the scale in the left hand (shown in green on the chart) are not part of the core positions, and are played with the 5th finger on the top of the scale (right hand) and the bottom of the sale (left hand).
It’s helpful to practice the core positions in three steps:
- Block out the core positions and play them up and down the keyboard in clusters of three and four notes at a time. This will help you clearly visualize the core positions in their entirety and get used to seeing the repeating pattern.
- Play up and down the scale one note at a time, but hold down the notes as you play and pause once the notes of each core position are fully down. This reinforces the muscle memory for the groupings of the core positions.
- Play the scale up and down one note at a time, releasing each finger as you play the next one (legato touch) but keeping the core positions in your mind’s eye as you travel up and down the piano.
The scale charts below will help illustrate the core positions of the G major scale.

Play the G major scale with hands together
Once you feel comfortable playing the scale with your hands separately, the next step is to put your hands together, but because the core positions don’t exactly line up when the hands play together, you may find it to be a bit confusing to focus on the core positions while playing the hands together.
For this reason, it can be more helpful to think about sync points than core positions when playing hands together.
Sync points are moments in the scale when your fingers unify and play together on either the same finger, or a group of fingers that are a mirror image.
In the G major scale, the first sync points occur on the notes B and E, when your 3rd fingers in both hands play at the same time:
The second sync point occurs in the two-note group of C and D, where your 1st and 2nd fingers form a mirror image position. (I sometimes refer to this position as the “crab claw” because it looks a bit like a pincer shape.) If you play this sync point together, you can feel the stability of these two notes and it becomes much less likely that you will second guess your finger placement when you shift positions going up or down the scale.
To practice the sync points, use these three steps:
- Locate each sync point on its own outside the context of the scale.
- Play the scale ascending and descending, but stop on the sync points and hold them (There’s no need to try and maintain a legato touch in this case.) Look at the sync points and visualize their place in the scale and what it looks and feels like at the moment they happen.
- Play the scale up and down one note at a time in a steady rhythm, visualizing the sync points in advance and then landing on them confidently with a slight accent as you play the scale.
Expand the G major scale to more octaves
Once you get comfortable playing the G major scale in one octave, you can try to expand the scale so it can cover more of the range of the keyboard. To add more octaves, follow these steps:
- For the right hand, instead of ending the scale with finger 5 after one octave, keep repeating the core positions until the endpoint further up the piano, whether it’s 2, 3, or 4 octaves higher.
- For the left hand, simply continue the core positions going up instead of turning back around after one octave. When descending, replace the 5th finger on the keynote G with the 1st finger until you reach the bottom, where you’ll finally play the 5th finger to end the scale.
Avoid common mistakes in the G major scale
Common mistakes or challenges you may encounter when practicing the G major scale are:
- Missing the F-sharp: Because there is just one black key in the G major scale, you may find that your hand is laid out too far onto the white keys, and by the time you get to the F-sharp, your finger hits the F-natural instead because it was lined up to play on just the white keys. To avoid this issue, make sure your finger tips are close to the median of the keyboard (where the ends of the black keys meet the middle of the white keys) and that your 4th finger (right hand) or 2nd finger (left hand) can comfortably rest on top of the F-sharp before it needs to play.
- Descending fingering: Watch out for a the common mistake of putting 4 on D in the left hand, especially when descending, instead of tucking your thumb under to start the group of four core position on D. If your thumb anticipates this shift by moving under a little sooner, you’ll be more likely to avoid this common issue.
