KeYTuner: A Hybrid Guitar Tuning System PALLAVI SANTOSH psanthos@andrew.cmu.edu 1
INTRODUCTION Clip-on tuner used to tune the strings of a guitar Automates the rotation of the peg, ensuring that it rotates until the string is tuned 2
OUTLINE MOTIVATION BACKGROUND THEORY MODEL CONCLUSION 3
MOTIVATION String instruments require regular tuning KeYTuner clips on to an instrument and tunes it automatically. 4
BACKGROUND Strobe Vibration Microphone All indicate state of tuning of the strings 5
THEORY f = fundamental frequency L = length of string T = tension in the string u = mass per unit length 6
THEORY L = pegR*alpha alpha = sin-1(pegY/pegR) pegX L L = pegR/((pegR^2 - pegY^2)^(1/2))*(pegV*pegX) pegY alpha pegR = radius of the peg (pegX, pegY) = points on the circumference of the peg alpha = angle subtended at the center L = length of arc 7
MODEL Event driven model: peg rotates until desired frequency is achieved Assumption: String is always too slack Efficiency condition: final frequency equals ideal frequency of = fideal Safety Condition: string never snaps otension < tmax Peg is modelled by: opegX' = -(pegV*pegY)/pegR opegY' = (pegV*pegX)/pegR 8
MODEL Rate of change of length of string with respect to rotation of peg: oL' = (pegR*pegV*pegX)/(pegR2 pegY2)^1/2 oL >= (1/2*fideal)*(tension/u)1/2 9
CONCLUSION KeYTuner proposes a model of a clip-on guitar tuner that automates the process of tuning. Presently models the tuning of one string but can easily be expanded to multiple strings. Multiple string instruments even! 10
