The note meets in a number of marked singing manuscripts of the middle of the XVIIth century and settles down in the same row with kinovarnye marks. On the basis of the analysis of the sources containing the given note, and also other ordinary singing manuscripts it was possible to define it music-scale character and to establish that on the value it is identical to the stepenaja mark « ». The reference to the musical-theoretical context of the epoch, Old Russian musical managements has allowed to reveal a source of the note: it is the third line of the index made by Ivan Shajdur for demonstration of the stepennye marks. It is the fragment of the litiynaja stihera of the Ascention of the Lord.
