If you haven't already read them, I can strongly recommend you read through Child's headnotes, skimming over the foreign analogues, but noting their existence. If you want to do this I can present you with some opinions based on my own experiences and more recent approaches. If the musical side appeals to you more, then Bronson is obviously the best possible start.

If Child's headnotes are the way forward then I recommend you start with his introduction and Dover Vol 5, p182, in the headnotes to Young Ronald. Perhaps his most telling statement.
