Tuesday - Sarah Walker with Catherine Martin

A selection of music including '5 reasons to love... Scandinavian strings'.

Take part in our daily musical challenge: identify a piece of music played backwards.

10am
Sarah's guest is the jeweller and trained classical musician Catherine Martin who, after travelling to Japan, discovered an ancient braiding technique that she spent four years perfecting and went on to use in her jewellery making. Her first piece of jewellery made the permanent collection at the Victoria and Albert Museum and she has since had exhibitions at the American Museum of Art and Design in New York, the National Museums of Scotland and the Worshipful Company of Goldsmiths. Throughout the week Catherine shares a selection of her favourite classical music, talks about physically stepping into Dame Janet Baker's shoes in a production with the English Opera Group and explains why she listens to the Bach Fugues whilst weaving precious metals in her work as a jeweller.

10.30am
Sarah places Music in Time as she discovers how Handel placed vocal prowess at the centre of the Baroque stage with his enduringly enchanting da capo aria Lascia ch'io pianga. A da capo aria's ternary form meant that singers could show off and add their own ornamentation to the final section of the song.

11am
As part of Radio 3's Northern Lights season, Sarah features recordings of major works by leading Nordic composers. Throughout the week Sarah explores music from northern lands as she showcases compositions by composers including Sinding, Nielsen and Berwald.
