Openmike said "so i copied the ABC text and tried to paste it in the ABC program and
it will not paste"

An ABC file is a simple text file containing one or more 'tunes'. You can make it in any text editor like Notepad for instance. ABC progs have an in-built text editor to make it easier and to display the result in notation as you type. The ABC program knows it's an ABC file because you've given it, or it already had, the _.abc_ suffix rather than _.txt_ . The tunes within that file must have a certain minimum structure to be recognised as a tune. At least the X:(tune number),K:(key) and then some letters to represent the notes etc. and then a space before the next tune X:(n).See a tutorial for details.

To paste an individual tune into ABCexplorer from elsewhere you must have a file open to paste it into. This can be one you've previously downloaded into your chosen place for ABC files and then opened in ABCexplorer, or it can be an entirely new file you've created from the 'NEW' button, and called 'Brantub' or 'Newtunes' or anything. Copy the whole tune including headers (e.g. X:) into the windows clipboard. Highlight the file you want to paste into, go into the menu 'IMPORT>import clipboard as a new tune, or press F9.

To import an entire file it's the same. Try this one:-

You can select and copy the whole text to the clipboard, make a new file from 'NEW , call it Atkinson or whatever you want, and press F9. The new file will be populated from the clipboard.
