FC - Fontana's copy
| Date: | (1837) |
| Title: | Quatre Mazurka |
| Dedication: | None |
Fontana's copy, made on the basis of the lost autograph [A]. After Chopin had introduced changes and complemented it, FC served as the basis for GE1. The Chopinesque interventions include:
- poco a poco cresc. - - - added four times in bars 17-23 and analog.;
- added g
notes on the 2nd beat of bar 29 and 61; - perhaps occasional corrections of slurs, e.g. in bar 10 or 15-16.
Fontana did not manage to avoid mistakes in this Mazurka, e.g. omission of the 3rd beat of bar 16 in the L.H. or the 
mark in bar 52.
In addition to engraving marks, in FC one can see in many places additions performed by a foreign hand, in pencil or crayon. They must have been made by the reviser (engraver?) of GE1, since all were included in that edition. The additions concern mainly accidentals, both cautionary and necessary – naturals to g1 in bar 5 and 13 or to b1 in bar 22 and analog. and a 
raising g2 to g2 in bar 39. In this Mazurka, a cautionary bass clef was also added at the end of bar 31 (end of page in FC). We do not consider these markings to belong to the text of FC.
