Of course I have the sheet music.
Here the sound recordings from the Ottoman Imperial Military Bands:
Here a different arrangement with an (I assume): Intruduction a la marche; andante and the Coda or final vivo part.
Here a version with an Introduction a la mazurka style. (Shared by our dear friend
@-Osman- )
and here a vocal version :
(But for the first part they sing a different text, from what I've showed in the sheet text.)
I conclusion, this march seems to be a very popular one in the past. Many different arrangements also from the well known composer and arrangeur Sinanian was made, and recorded.
From the different military band records we can also notice that even the official Version could have variations. But the characterstic main part in Semai usul seems always to remain (with little changes) while the Introduction and the Coda/ Final part is from arrangement to arrangement different.
Looks like a popular "must have" for a music repertoir during the II. Constitutional Reform Period. A Patriotic march and relict of the 1900/1910s . . .
