Beginners often get overwhelmed by the number of music notes to remember eg F#, Db, A, etc. Here's some basic tenets that may be helpful:-

* There are only 12 different musical tones

* Each a half-tone apart

* The 13th tone repeats the 1st tone but at one octave higher (when ascending) or lower (descending).

******************************************************************************

* By convention, we use only 7 alphabets i.e A, B, C, D, E, F and G to represent 7 of the 12 tones.

* Again by convention only two pairs B-C and E-F are naturally a half-tone apart. The rest are a whole tone apart.

* To represent the other 5 of the 12 tones, we use accidentals.

* When ascending, we use this accidental '#' (pronounced 'sharp') to 'nudge' the alphabets a half-tone higher. Hence the 12 different musical tones, each a half-tone apart, when ascending, can now be represented as follows:-
A A# B C C# D D# E F F# G G# A' (this 13th note A' is one octave higher than first A).

* On descending, we use this accidental 'b' (pronounced 'flat') to 'nudge' the alphabets a half-tone lower. Hence we get:-
A Ab G Gb F E Eb D Db C B Bb A^ (this 13th note A^ is one octave lower than first A).

Also notice that the following pairs are the same notes:-
A# same as Bb (A A# B.. ascending; or B Bb A... descending)
C# same as Db
D# same as Eb
F# same as Gb
G# same as Ab

*********************** Now Let Our Imagination Flow ******************

Imagine if you are a music composer and have to compose for a music instrument that can play 4 octaves i.e you have 48 (12 tones/octave x 4 octaves) musical tones each a half-tone apart.
Given 2 minutes for this short piece i.e. 120 seconds; we divide every 4 seconds into 1 measure (bar) - therefore we have 30 bars in this piece.
Now imagine a few sheets of paper, write your music score - 30 boxes horizontally to represent 30 bars; each bar 4 seconds.
Going horizontally, we can use any 4 tones, one tone for each second; or 8 tones, one for each half-second; or 16 tones one for each quarter-second; or any combinations to complete the 30 bars. (If there are more tones in one bar, obviously fast tempo).
Vertically, we can also add tones to each other, giving us chords in any or all of the 30 bars of music......

* The different combinations of notes with different time configurations is astounding. Who knows you may end up creating a unique sound and rhythm you can call your own!!
