My guess is that the dots represent vowels, and the squiggly lines are consonants or consonant sounds. It looks a bit like Teeline shorthand, but can't be Teeline as that wasn't invented until the late '60s. I'm wondering if it works on the same principles though. Here's my guess:
Line 1, starting from symbol 3: ".... summer dance together with"
Line 2, last symbol: "Eleanor"
