The life of a videographer is subject to spontaneity as well as good planning. 
If fortune is on our side, then we might capture a “memorable moment“.

Here is one of them.  A wonderful performance, captured with good light and a steady shot, and with a decent sound quality using the ever-ready Zoom H4n recorder with a built-on microphone pair.
No time to set up, and only one error that a short rehearsal might avoid – the H4n being placed exactly in line with the pianist’s head !
