Naming of Musical notes
In the western scale of Music, Notes are named by first 7 letters of the English Alphabet.
A,B,C,D,E,F,G - only these 7 alphabets.

Now the question is can we properly address all of the notes using just only this 7 alphabets?
Answer is yes. We can ..
As soon as i said yes , you will be thinking either ->
each of the alphabets are used for one or more than one notes.
or -> i am not getting what shit you are speaking.
and the thing is we can call different frequencies by only one name or one alphabet..
question arises why the thing is like that? Can't we define different names for each of the notes?
because we don't need to give different names to every note. Sound frequencies which are multiple of octaves apart (don't think of multiple of octaves right now , we will discuss it in future) carries the same characteristic of sound that's why we call it by same name .
example : a note A is 220 Hz. Another note which is 1 octave apart having frequency 440 hz & another note which is 2 octaves apart having frequency 880 Hz.
We will call all the three frequencies 220 Hz,440 Hz,880 Hz by the same name 'A'. Though their frequencies are different but they have same characteristics in their nature of sound .
(because they are octaves apart)
If you are unable to understand till it's perfect !
Just one reading is what you need at this stage as a beginner.
As soon as you read more & learn more things will become crystal clear.
In the western scale there are total 12 notes - 7 natural & 5 accidentals(sharp/flat)
we can draw a circle of notes like this :
these 12 notes cycling repeatedly along the frequency spectrum. From A to G(clockwise dir) denote increase in pitch & A to G anticlockwise the pitches are decreasing.
Suppose A =220 Hz we go on increasing the pitch,
note A# =233 Hz,
note B =247 Hz
so on....
note G# = 415 Hz
note A(after 1 cycle A comes again) = 440 Hz.
note A# = 470 Hz ...........
we can differentiate different octaves by adding a suffix to the note example,
A3 =220 Hz, A4=440 Hz where 3 or 4 tells that this note is 3 octave higher or 4 octaves higher from the base frequency of the note A i.e. A0=27.5 Hz(the starting A after 20 Hz limit)
so basically that's the overview of notes along the frequencies.
To make a summary,
these 12 notes make a packet of notes or sequence of note & this packet or sequence are repeated over & over as long as we climb up the pitch .
& the notes will be repeated like-
20Hz....................(A,A#,B,C,C#,D,D#,E,F,F#,G,G#),(A,A#,B................20KHz
& we can give suffixes to note names for different packet numbers or sometimes we just don't need to.
