From the My scores page click ‘Add a new score’. Browse for the score, confirm ownership and Terms and conditions and then click on Upload File. The new score will be added to your list of scores. Check the status – if there is a red symbol displayed, hold your cursor on the symbol to get an explanation. Make the necessary correction so that the red symbol is replaced by a blue tick or check. Note that the options to replace, edit or view score details, view statistics and delete the score are still in view and available.
If you have a lot of music to upload to Score Exchange, then you can also use the bulk upload option, which can be a faster then uploaded each file individually.
