Forbes magazine's annual survey of billionaires reveals that of 691 names on list (up from 587 last year), only 10 are single guys. So who is this mystery Billionaire Playboy anyway?

The single boys include 21-year-old German prince Albert von Turn und Taxis; Stefan Quandt, 39-year-old heir to BMW fortune; and Google boys Larry Page and Sergey Brin.

The billionaires' combined net worth was $US2.2 trillion ($A2.78 trillion). Microsoft's William Gates III topped list for 11th year, with $US46.5 billion. Close behind was investment guru Warren Buffett with $US44 billion. It couldn’t be Warren he has made arrangements to take his money with him and he is probably getting to old anyway and I don’t think he ever had an eye for ladies.

Media mogul Kerry Packer, worth $US5 billion, is richest Australian and ranks 94th. Shopping centre king Frank Lowy ranks 151st, with $US3.6 billion, and Richard Pratt, at No. 321, is worth $US2 billion.

When I first started learning guitar I would strum along happily until chord change and then my right hand would stop while I changed position of left.

This makes your playing sound terrible. In fact if you can keep that right hand strumming or picking sequence, you will sound good. If you are a bit slow with your chord changes and strum some open strings in between you will still sound good. But lose that rhythm and everybody knows that you are messing up.

Here are my top three tips for getting past this learning stage.

#1 Play open strings for last beat in bar so you have time to change chord shape. For example if your are to play | G G G G | D D D D | C C C C | instead play | G G G O | D D D O | C C C O | where O is a strum of open strings. Listen carefully and you will notice a lot of guitar players do this. And it sounds just fine.
