In the same way that people can have a mixed background, with parents originating in different continents, so too music can be a blend of influences. A particular rhythmic pattern, or a characteristic instrument, is enough to give a traditional feel to music, even when it has been composed recently. It is easy to recognize the presence of a bagpipe or a tabla in a piece of music. The young are usually much less offended by the dilution or adaptation of songs this way. Equally an electric guitar can be added to an old song. The relevant factors may include instrumentation, tunings, voicings, phrasing, subject matter, and even production methods.
