Finger binary this is (512 + 256)/1024 = 768/1024 = 3/4. If using only one hand (left or right), it would be (16 + 8)/32 = 24/32 = 3/4 also. The simplification process can itself be greatly simplified by performing a bit shift operation: all digits to the right of the rightmost raised finger (i.e., all trailing zeros) are discarded and the rightmost raised finger is treated as the ones digit. The digits are added together using their now-shifted values to determine the numerator and the rightmost finger's original value is used to determine the denominator. For instance, if the thumb and
Thumb position the third ledger line in bass clef notation for the double bass). To play passages in this register, the player shifts his hand out from behind the neck and flattens it out, using the side of the thumb to press down the string. When playing in thumb position, the use of the fourth finger is replaced by the third finger, as the fourth finger becomes too short to produce a reliable tone. Bass instruction books often teach thumb position by having the player place the left-hand thumb on the high G note (on the third leger line in bass clef
