Here’s the video for Playford tune The Beggar Boy, from the 1651 manuscript – it was included in subsequent editions right through to the 7th in 1686, and Chappell (1859) notes that there are several ballads written to the tune, as tended to happen with popular tunes.
And here are the dots:
Here are the dots in PDF form, for those who want to print them out.
We created contrast between sections with drone-like minor chords in the A section and swifter changing major chords in the B section. I’ve tagged the tune as both major and minor as it can be harmonised as either, giving a different character.
We created a groove for the A section by picking out notes from the D minor and C major triads. Since Dm and C are neighbours, it’s possible to move between the chords in a scale pattern. Here’s a link to a chart explaining this: for each of the main beats listed at the top, pick a note from the coloumn beneath. There is an example of how you could do this at the bottom, with notes highlighted in red. You might want to print this sheet out and circle one note in each column to create your own part.
