Though initially it was conceived as "Eleven Piano Recital Pieces", one of the pieces was dropped and used as a bagatelle in Bartók's Fourteen Bagatelles. However, he was required by a contractual obligation with his publisher to write eleven pieces, so he wrote a dedication which is not numbered but serves to complement the set. For this reason, this set and his set of bagatelles are related, both in their
Instrument error five-pound weight could be measured on a scale and then the difference between five pounds and the measured weight could be the accuracy. The second definition makes accuracy related to calibration, while the first definition does not. The instrument error is not like random error, that can't be removed. Sometimes the removal of instrument errors are very easy, but it is case dependent. In Engineering instruments, like voltmeter or ammeter for example, the instrument error is very difficult to remove. Ammeter has built in resistance, which can't be removed either way. So the only way is to minimize it. On
