string vibrations plucking vs bowing envelope tunings specific instruments Review Strings Normal modes of vibration of string are demo
Fundamental mode _______________ fits length of string pitch, based on v 1 T f1 2L 2L
Pitch of String v 1 T f1 2L 2L to change the pitch, can change calculate v why isnt it
String Harmonics The nth mode is its frequency is its wavelength is There are length of string = 1st harmonic is
2nd harmonic is Plucked Modes Normally, the motion is but a A string plucked at center has shape of a which A string plucked
will not have Recall: harmonics lend Plucked String The triangle wave in plucked string Bowing
Bow also pulls string to a point but bow until the wave then the string before being pulled again. Occurs Note: If you bow too gently, If you bow too hard,
Bowed Modes The wave in a bowed string is more like a which has
The harmonic content, of a bowed instrument is very different from Envelope of Plucked String The envelope of a plucked string has a rapid ____ and a long ______ no sustain/release
the harmonic content of the decay becomes _____with time. Envelope of bowed String The envelope of a bowed note has a less rapid _____ and a quick _____. Sustain lasts as long as bowing continues sustain has fairly constant ______
the release is similar to decay of plucked string. Violin Strings G3, D4, A4, E5 each tuned a Recall a fifth is a ratio of an interval of an interval of
Violin Demo G3, D4, A4, E5 Can you play G4 on D-string? by making the string play harmonics? Demonstrate open notes (), fingering (__), tuning (__), interval, pizzicato vs bowing, play something Guitar Strings
