Letter to an editor_What my favouirite national custom is. Dear Sir or Madam, I am writing to you because I would like to say what my favourite national custom is. Although there are a lot of interesting famous customs in Spain, such as ‘Los San Fermines’, the one I like most is ‘The International Guitar Festival of Córdoba’. This custom has been celebrated since 1980 and has become one of the most important cultural events we have in Córdoba. Along last years, many famous musicians have been demonstrating their high level of performance. During the event, you could attend concerts on classical, flamenco and medieval guitar. Furthermore, learning to play the guitar has always been an educational part which people like very much. Besides, I like this custom because of my love for music. It is known by teachers how much I used to enjoy music since I was in my first school years. Moreover, it is celebrated in my own town in June. If I were you, I would try to book your tickets on the internet two months before because it runs out early. Thank you very much for give students the opportunity to express their likes for the magazine. Yours faithfully, Carmen M.
