a good vintage

I am trying to coax some more tone out of a harp I made last year.  It takes about 2 weeks to make the frame and about 6 weeks to load 2 1/2 tonnes of stress, 122 strings and get it stable.  It takes a good 6 months of constant tuning to keep it stable and only then can you listen!  No matter how you try to replicate a favourite harp they are all different.  Suddenly when they are 2 or 3 years old they start to ‘sing’.  They then get better and better – just like a good wine and they’ll go for months without tuning.
