Abstract
The play-wear tests on the strings from high carbon steel were realized by using a long necked bağlama stringed instrument. These tests were carried out by reciprocating with the finger on the sound table for different times. The stick-slip wear and striking effects were observed on the strings by AFM. A noticeable increase was detected in the values of surface roughness obtained from Do, Fa, and Si pitch-strings and the chest region-string depending on the beat amount. Hence, it attracts attention that the roughness values decrease while it is passed from 1000 to 3000 beats and from Do pitch to Fa concerning beat amount and pitches. However, such an increase was not detected in the Si pitch-string and the chest region-string, and whilst passing from 3000 to 6000 beats, on the contrary, the average surface roughness values showed a tendency to increase.
