#BBCtrending: Playing the piano to riot police in Ukraine
When demonstrations in Ukraine first turned violent, Markiyan Matsekh decided the best way to communicate a message of peaceful protest was to place a piano in front of police lines and play a little classical music.
In the following months, the piano - painted in the colours of the Ukrainian flag and the European Union - has become something of a sensation on YouTube.
#BBCtrending spoke to Matsekh about the piano and the social media tactics of those behind the #EuroMaidan hashtag.
