Rhythm Basics for Norteño Accordion: Pulse, Tempo and Counting
Rhythm from zero for button accordion: feel the pulse, understand tempo in BPM, count in two and four, and change the bellows exactly on the beat.
Pulse: the beat under the music
The pulse, or beat, is the steady tick you feel under a song: where people clap or tap a foot. Every beat is the same distance from the next. Before you worry about notes, your playing needs to sit on that pulse.
Put on any music you like and tap the pulse with your foot. If your foot keeps going when the melody gets busy or pauses, you are already feeling the beat.
Tempo and BPM
Tempo is how fast the pulse goes, measured in beats per minute (BPM). At 60 BPM you get one beat every second; at 120 BPM, two beats every second. A higher number is a faster tempo.
Changing the tempo changes how close the beats are, not how even they are. Slow music still needs a perfectly steady pulse, and slow practice is where that steadiness is built.
Counting in two and in four
Beats are grouped into bars. In 2/4 you count “1 2, 1 2”; in 4/4 you count “1 2 3 4”. Beat 1 of each bar is the strongest. Many norteño polkas and corridos are counted in two, so “1 2” is a count you will use a lot.
To fit two notes into one beat, add “and” between the numbers: “1 and 2 and”. The numbers are the beats; the “ands” are the halfway points, called off-beats.
Rhythm on the accordion: the bellows keep time
On a diatonic accordion, push and pull give different notes, so many melodies change the bellows direction often. A late direction change makes the note late. Practicing clean changes on the beat is rhythm practice and bellows practice at the same time.
Try this on middle-row button 3: four beats on the push (C), four on the pull (D), counting out loud. Then two and two. Aim for the new note to start exactly on the count, with no gap.
Practicing with a metronome
Start at a tempo slow enough that you never hesitate, such as 60 BPM. When an exercise is clean three times in a row, raise the tempo a few BPM. If it falls apart, go back to the last tempo that worked.
Count out loud even with the metronome on. Saying the numbers keeps you in your place in the bar, which matters once you add bass and chords.

Our free lesson “Pulse and tempo” lets you tap along at different tempos and checks your timing automatically, then has you keep a steady pulse on one accordion button. No account or card is needed.
