BEGINNING FORM

The beginning of "Stairway to Heaven" by Led Zeppelin introduces a repeated set of notes played by a guitar and recorder playing along with it. The timbre of these instruments are completely different and can be distinguished from each other while they are being played together at 0:28 - 0:32 and a slight crescendo is heard. At 0:44 - 0:46, the pitch of the recorder increases and another crescendo is heard building up at 0:47 - 0:49. This crescendo prepares for the first verse and seems to set a certain mood for the audience before the lyrics are heard. One thing I found interesting was when the guitar went towards the higher notes, it slowly went into a slight crescendo, but not as intensified as the one before the first verse.
