If not, generate a faster or slower clicktrack, and time-shift it to the same starting position as before. Then, if the song really has an accurate tempo throughout, and the click track nails the exact tempo, it should stay in sync through the rest of the song.

Make a not of the time shift that is required: how many seconds and milliseconds. Use Audacity's time shift tool to move the click track to begin on the first identifiable beat in the song, past its intro. have an audacity track with the song and one with a generated clicktrack and want to align the 83 bpm clicktrack with the beat of the song There is also a metronome feature to assist with timing, another great feature for children.The underlying question, dug up from comments: You don’t have to be a exceptionally gifted musician to create music because there is an 1-4 setting auto-play feature, so you can choose your note E A D G B F etc. The children will love this program and the really great thing about it is the differentiation for pupils. Other instruments include a keyboard, drums, Audio recorder, ‘smart strings’ and a ‘smart bass’.

If you don’t have a guitar it’s not a problem as there is a ‘smart’ guitar program built in. I can then record myself playing with all kinds of amplifiers and effects, even drumbeats and other instruments. I can plug my guitar into my ipad using an iRig which converts my amp lead into a microphone jack. I have the iOS version (can’t afford a mac) and I love it. GarageBand is a software application for Apple computers running OS X or iOS that allows users to create music using the embedded instrument or by connection to an external source.

I have used both programmes for music recording and editing. Just wanted to share some information about Audacity the free audio editing programme and GarageBand by Apple.
