Musicians usually benefit by learning an air from a singer. This is helpful in understanding the phrasing, mood and inflections of the song. Knowing the words of the song also helps the musician appreciate where the song is coming from emotionally. Most airs are not in any strict tempo. The structure of these airs is obviously the same as the songs – generally simple (e.g. AABA).
