Cathedral Square

There has been a renovation of the square in front of the cathedral in my home town of Worcester with lots of new bars and restaurants. The tiles in the centre have a pattern on them which I have on good authority that they were originally designed to be full sheet music, but they were simplified into a more stylised design for their final form. Here’s a photo which shows the first two of the four rows.

You'll notice that the stave only has 3 lines rather than the full 4. I would like to identify the music, which I'm presuming is from Elgar since he was involved with the Cathedral behind the square and there is a nearby statue of him. The four lines of music look quite different from each other and I suspect they are from different pieces. Below are the bars converted into numbers with a key at the bottom. That there are 7 distinct numbers this feels like it may well be the melody of the music.

The dots refer to which way the note continued, the dashes to where there were gaps (drawn roughly to scale) and the question marks to where it was ambiguous (the last line didn't convert nicely into the grid that it should be because of the placement of the tiles). If this is a normal treble clef then we should have 0=d, 1=e… 6=c.

If you do crack it, can you tell me please?
