Scales for Norteño Accordion: C, G and F Major Button by Button

Play the C, G and F major scales on a three-row G/C/F button accordion, with every button and bellows direction, plus tips for practicing them cleanly.

Why scales matter on the button accordion

On a diatonic accordion a scale is more than a finger exercise. Because every button has a push note and a pull note, a scale trains your fingers and your bellows together. Each row of a three-row accordion has its own major scale, and most beginner melodies in norteño music stay inside one of them.

The button numbers below are for a G/C/F accordion, counted from the chin end. On an F/B♭/E♭ instrument the same buttons work, but every note sounds a whole step lower.

C major on the middle row

Start here: no sharps or flats. Going up: button 3 push C, 3 pull D, 4 push E, 4 pull F, 5 push G, 5 pull A, 6 pull B, 6 push C.

Notice the pattern: push and pull alternate on each button, and then two pulls come in a row (A, B) before the top note. That spot is where most beginners stumble, so practice it on its own. To continue up a second octave: 7 pull D, 7 push E, 8 pull F, 8 push G.

G major on the outer row

G major has one sharp, F♯ (Fa♯), and the outer row provides it. Going up from the G near middle C: button 5 push G, 6 pull A, 6 push B, 7 pull C, 7 push D, 8 pull E, 9 pull F♯, 8 push G.

Watch the finish: the two pulls are on buttons 8 and 9, then you come back to button 8 on the push. There is also a lower G scale starting on button 2: 2 push, 2 pull, 3 push, 3 pull, 4 push, 4 pull, 5 pull, 5 push.

F major on the inner row

F major has one flat, B♭ (Si♭), and the inner row provides it. Going up: button 3 push F, 3 pull G, 4 push A, 4 pull B♭, 5 push C, 5 pull D, 6 pull E, 6 push F.

This is exactly the same button pattern as C on the middle row, just one row closer to the bellows. Once your hand knows one, the other comes quickly.

Accompanying a scale with the bass

Each row has a matching bass pair on the bass row printed first on the chart. For C, use the buttons labelled c and C; for G, g and G; for F, f and F. Because the bass buttons follow the bellows, the same pair gives the dominant on the pull, which fits the pull notes of the scale.

Start with one chord press per scale note, then try bass on beat 1 and chord on beat 2 while the right hand plays the scale in slower notes.

Going down, and common mistakes

Coming down is the same path in reverse, and it often feels harder because the two pulls now come first. For C on the middle row: 6 push, 6 pull, 5 pull, 5 push, 4 pull, 4 push, 3 pull, 3 push. Say the bellows direction out loud the first few times: “push, pull, pull, push…”.

The most common mistakes are changing the bellows a moment before or after the finger, pressing the right button in the wrong direction, and speeding up on the easy part of the scale. Slow, even notes fix all three.

How to practice scales well

Use a metronome at a slow tempo and give every note exactly one beat. Play up and down without stopping. Change the bellows and the finger at the same moment, so there is no gap or bump in the sound. Raise the tempo a little only after a few clean runs in a row.

Common fingerings use the index, middle and ring fingers on three neighboring buttons, but players vary, so pick one fingering and keep it consistent. Our free C-scale lesson lets you hear and play the scale on an interactive map before you try it on your accordion.
