The opening morning of the conference was excellent value and was clinically relevant at least to me, the afternoon offering less so. I excused myself at lunch and walked to the Museum of Musical Instruments (Musikinstrumenten-Museum) via The Tiergarten. 

This is an huge Park in central Berlin. Surely I was dreaming when from the lush tropical forest beside the track I heard the by now familiar tones of a Treble Recorder. It was moreover being played by an expert. I cautiously left the path and as quietly as possible navigated towards the music. There he was : an old man dressed in black and happily playing a baroque piece with trills and ornamentations worthy of any professional. He finished the piece with a flourish. I spontaneously applauded, he laughed with surprise and we chatted, confirming he had being playing since a child. I confessed that I was an old man playing like a child. 

Thence to the Museum and its well worth a visit. Harpsichords and pianoforte abound. Invest in the audio guide and you will hear musical examples on the actual instruments.

Finally as my iPhone confirmed i had walked 37km, i went to the nearby Italian Trattoria and had s pizza which the menu boasts are 34 cm tall.
