This week Joanna and Stephen are joined by a very special guest, Stephen's personal piano tuner, David Widdicombe. From concert grands, upright 'domestics' and honkytonks, David has tuned them all. Having worked with the world's most prestigious piano maker, Steinway, for 3 decades David tells us about his life working alongside the world's most gifted players, how fractions of millimetres make all the difference and how to find the perfect 'temperament' from your own “Joanna”.

This week we’re diving into two bohemian heroes of classical music, Bohuslav Martinů and Leoš Janáček. Stephen remembers encountering the music of Martinů at Cambridge, and being confronted by the "pure simple joy" of it. From the lyricism of Martinů, we work back towards Janáček – another gifted Czech composer – and get to grips with the fairy-tale essence of The Cunning Little Vixen, Sinfonietta and the exultant Glagolitic Mass. Strap in. The Bohemians have arrived.

Which note could the Maestro not live without? Where are all the female composers? And is there a better quintet going than Franz Schubert's Trout? In this mini episode Joanna puts your questions to the Maestro.

This episode is all about the written language of music, the 'hieroglyphs' or 'blobs on the stave'.

In this mini episode, Joanna and Stephen explore the most pressing questions. What is the Maestro's preferred sobriquet? Music that sounds like it's from a different dimension, and how one should conduct music for the love of three oranges?

Is it a faun? Is it moonlight? Yes, it's Claude Debussy! Over the next 30 minutes, Joanna and Stephen discuss the musical development of French impressionism. We see how three composers, Debussy, Ravel and Boulez, summoned images through sound and set the imagination free.

In this mini episode, Joanna and Stephen field more vital questions from listeners, such as, why does transposition jangle the Maestro's mind? Which musical keys suit certain moods? And most importantly, what not to wear when meeting the President?

Is there anything quite so majestic as the British brass band? Joanna and Stephen describe their first encounters with these ensembles, how they evolved and which pieces reach out to the soul. With the onset of the Industrial Revolution, brass bands first appeared as a means of fostering community ties among workers. These bands have since become popular in various contexts, from marches and competitions to concerts and even movie scores.
