Alison- Thank you for your reply on this subject. The core problem in my mind is that most harpists, especially at an advanced level, have spent years playing pieces in which they themselves have written in the pedals. So for each of these harpists, the pedals follow their particular system: between the staves, below the lower staff, left above right, right above left, green ink, red ink, pencil, etc. etc. etc. The variations are endless, and always in the hand writing of the harpist. My feeling is that we all need to learn to read pedals where and how they are written or printed. Many rental parts for example have correct pedals hand written in, but often each harpist who uses the part rewrites them, just so they will look the way they are used to seeing them.
I would suggest to ALL harpists that, as a learning exercise, you try using a part the way the pedals are written in, without changing anything. Just get used to reading other harpists pedal writing, provided of course that they are correct. I think that, in time, you will become more adept at reading any and all pedals, which will be to your benefit. Stated another way, reading pedals is just one more skill that you need to develop to be able to learn music quickly and accurately. Being able to read pedals wherever and however they are written will save you a lot of unnecessary work.
