yes,if you can afford, a computer all very well,if not,standard musical manuscript,and for those students,who wish to learn by ear,using a mobile phone to record.
I can afford a computer,and find going to you tube to hear good musicians such as Joe Burke more useful ,as soon as I see a tune in abc I go to concertina net and convert it to standard notation .
mean while most of the third world cant afford electricity ,let alone computers,and the way things are going there are many in the developed world who wont be able to afford computers soon.
