নমস্কার guys ! I wanted to know what do আপনি call ( Do - Re - Mi - Fa - Sol - La - Ti - Do ) ?? I know they are notes but because I'm a beginner in learning পিয়ানো so I don't really know the other notes!

They're just different names for the notes- A, B, C, D, E, F, and G. It depends on the key signature what notes they actually are (they could be sharp অথবা flat). For example, in the key of C Major/A Minor there are no sharps অথবা ফ্ল্যাটের (all white keys), but in the key of C Minor, As, Es, and Bs are flat. This is a picture of the C Major Scale. Do can be substituted for one, Re for two, and so on.

Hope I could help!

EDIT: Oh yeah, and if আপনি need to orient yourself, Cs are the white keys directly below each set of two black keys.

they're just the notes of a scale, ive never heard them called anything else

It is a scale. If আপনি may know... the 1st "do" is the lowest and the last "do" is the highest. Everything in between are the steps to get to the highest "do"
Hope that helps.

Do a deer, a female deer.
re, a drop of golden sun...
:D

Do, a deer a female deer
Re, a drop of golden sun
Mi, a name I call myself
Fa, a long long way to run
Sol, a needle pulling threed
La, a note to follow Sol
Ti, a drink with জ্যাম and bread
And that brings us back to Do!!!! :)

They're just notes with a different name. That lady in the sound of সঙ্গীত made it 'cutesy'.
A B C D E F G
Treble clef অথবা খাদ clef? Cuz base clef is different, In terms of the order in the bars...

They are called solfège syllables and are used to teach pitch.
