The Camellias immediately bring to mind the opera- ‘La Traviata’ – which literally means ‘The Fallen Woman.’ The delightful music was composed by Verdi and based on a novel and play by Alexandre Dumas in 1852 entitled - ‘La dame aux Camelías’ or ‘The Lady of the Camellias’, but I’m not going to discuss her reputation!
Apart from the famous song – ‘Libiamo‘ (The Drinking Song), my favourite melody and aria is – ‘Di Provenza il mar il suol’ (of Provence, the sea, the soil). I have played it at a few pub sessions! Listen to it on YouTube, which has a few versions. Try the version by Placido Domingo, starting at 1 min 30 secs on the video to 5 mins 30 secs. You may prefer other versions, including a Karaoke version, instrumental version, also sheet music!
