Review relationship between string length, tension, and pitch
GOOD MORNING! Today we will: graph the relationship between: string length and frequency string tension and frequency take a short online quiz watch a 5 minute video on mosquito tones write a short (but accurate and scientifically precise) response describing how a guitar makes music Please do before the bell: get your lab book get 1 whiteboard/marker per table get a netbook (leave closed on your desk for now)
theHOW DO GUITARS MAKE relationship between string MUSIC? length/tension to pitch
WARM-UPAs string length _______, frequency _______.
