1 4 1 1
4 4 1 1
5 4 1 5

or

1 1 1 1
4 4 1 1
5 4 1 5

should be
Bb7 Bb7 Bb7 Bb7
Eb7 Eb7 Bb7 Bb7
F7 Eb7 Bb7 F7

if you can look at the “circle of 4ths” chart, and visually memorise what the chart looks like.

Then you can recall the I-IV-V chords starting on any chord on the chart.

Ex if your I chord is a Bb7 chord, then go anti-clockwise and you will visually recall the IV chord which is a Eb7 chord, and from Bb7 go clockwise and you will recall the V chord which is a F7 chord.

Similarly if you are into Jazz where you play the II-V-I chords.

ex if your II chord is a G chord, then go anti-clockwise and you will visually recall the V chord which is a C chord, and if you go anti-clockwise again, you will visually recall the I chord which is a F chord.

so if you visually remember where all the letters are on the “Circle of 4ths”, then you can quite easily recall the I-IV-V or the II-V-I chords starting on any chord

Herewith a tasty answer! Enjoy! 🙂
