Playing the same note on every string is one of those exercises that sounds simple but delivers a huge amount: you learn where notes live across the whole neck at once, you train your ear to recognise when you’ve hit the right pitch, and you pick up one of the most important sequences in all of music along the way.
What you’ll get out of this lesson: A practical drill — working through each note of the cycle of fourths and finding it on every string — that builds genuine fretboard knowledge from the ground up.
The cycle of fourths
The sequence of notes used in this exercise is the cycle of fourths: C, F, B flat, E flat, A flat, D flat, G flat, B, E, A, D, G, C. It’s one of the most important patterns in music — a sequence every serious musician eventually needs to know. For now, you don’t have to memorise it; it’s written out below. But spending time with it through this exercise is a natural way to start absorbing it.
How the exercise works
Start on C. Find it on every string, from the lowest to the highest, and play each one in turn. When you encounter an open string, also play the 12th fret — they’re the same pitch, and hitting both reinforces the octave relationship. Then move to F and repeat. Then B flat, E flat, and so on through the whole sequence. Always be listening: your ear will tell you whether you’ve landed on the right note or missed it, and that active listening is part of what makes the exercise so effective.
This is one of the best exercises I have for learning the fretboard. Always be listening — you should be able to hear if you’ve missed the note or made the right note.
Taking it further
Once you can work through the full cycle at a comfortable pace, try doing it without the reference chart. Then try starting from the highest string and working down. Eventually, aim to be able to call out a note and go straight to it on any string without working up from the lowest string first — that’s when the fretboard starts to feel genuinely under your fingers.
Your homework
Work through the full cycle of fourths — C, F, B flat, E flat, A flat, D flat, G flat, B, E, A, D, G — finding each note on every string in order. Do this once a day this week, using the reference chart as needed. By the end of the week, see if you can get through C, F, B flat, and E flat from memory without looking.
