G major: piano-course lesson 2
Originally published on jonatascastro.com. English edition translated and revised 01 Oct 2026. Historical examples are identified in the text.
This is the second lesson in my piano-course series. After starting with C major, we move to G major.
G major has one sharp: F♯. Its notes are:
G – A – B – C – D – E – F♯ – G

What the lesson covers
In the video, I play the scale over two octaves and demonstrate the fingering. At the end, I also play the C-major, D-major, and G-major chords.
Together, those chords are the IV, V, and I chords in G major. Playing them after the scale helps connect the notes you are practicing with the harmony you will hear in songs.

How to practice
Start with one hand at a time. Keep the F♯ consistent, especially when descending. Once each hand feels comfortable, combine them at a tempo that lets you play evenly.
The next goal is not speed: it is a smooth thumb crossing and a steady pulse across both octaves.
