Notes:

Chord progression:
| I | V | I | IV | I | V | IV | I |
Example in Bb:
| Bb | F | Bb | Eb | Bb | F | Eb | Bb |

IMO, with a progression like this, very straightforwardly Bb major and always resolving back home to the Bb, you don’t need to follow the chords as much as you just need to time your resolutions so that you land on chord tones that belong to the Bb chord as the progression returns to Bb.
