Difficulty: Moderately Challenging
Step1
Get good at marking off rhythmic "bars." In a 1-4-5 pattern on the bass guitar, you're going to rely on rhythm to make your progression recognizable and catchy. Practice the four-beat bar as a measure of your playing.
Step2
Begin at the beginning. There are many variations on the 1-4-5, but the most basic and recognizable one is based on a series of bars, and it starts on 1, which is any note depending on what key you're in. The lowest and "open" key is E, since your bass guitar's lowest string is tuned to E. So for a playable example, let E be 1. Play two bars of the E note.
Step3
Go up to your 4, in this case, the A note, for one bar.
Step4
Move back down to your 1, in this case E, for one more bar.
Step5
Play one bar in your 5, which is B.
Step7
Practice playing this progression until you recognize it from any rhythmic blues music you may have heard before. Add "extra" notes like the G on your low string within the bars, always resolving to your E, A, or B at the end of a bar. Over time, your 1-4-5 progression will get clearer, sturdier and more elaborate.
