INTRODUCTION TO THE KEYBOARD.
A Tutorial From The Desk Of The TYAGOG's Music Class.
I believe that, we all must have come across the word 'Keyboard'. No one can deny it. If there's anyone who would, then, the person shouldn't be existing in our world. But, what is a keyboard then? To the layman, a keyboard generally means the collection of keys on a board. What do we mean by this? We don't just have the musical keyboard, we also have the computer and the smartphone keyboards. The similarity between all the keyboards is that, they all have boards and keys on them. However, our focus here is the musical keyboard. The computer keyboard serves as an input device in the sense that, it sends in commands to the system and these commands would display on the monitor, which is output device.
Meanwhile, the musical keyboard has a different mechanism. It is a full system on itself that serves as both input and output. It creates its own instructions and provides a feedback for us. That is why, we say that, the musical keyboard is defined as, A device with keys of a musical keyboard, used to control electronic sound-producing devices which may be built into or separate from the keyboard device. A keyboard or piano comprises a soundboard and metal strings, which are struck by hammers when the keys are depressed. The keyboard has black and white keys and these colored keys guide the understanding of the working of the keyboard. When you press these keys with your fingers, little hammers hit wire strings inside the piano which vibrate to produce musical notes.
THE DIFFERENCE BETWEEN A KEYBOARD AND A PIANO.
Many people think that, the keyboard and the piano are the same. Well, they're almost, but they're not. Their structure and mechanism might be the same, but they have slight differences in their functions. A keyboard is not really an instrument, but a piano is. The keyboard is an instrument that houses other instruments. It is A component of many instruments including the piano, organ, harpsichord, etc. DO you know that, on the keyboard, we have even drums and voices? I know, you don't. ☺

MUSIC ALPHABETS AND THEIR POSITIONS ON THE KEYBOARD.
There are majorly seven keys in music and they are:
A,
B,
C,
D,
E,
F, and
G.
However, on the keyboard, these alphabets (now referred to as keys) would normally start from C, and so, would be rearranged as:
C
D
E
F
G
A, and
B.
But then, we've only represented the white keys on the keyboard. There are black keys on the keyboard as well. Each of these whites have blacks apart from B and E.
Literally, we often refer to those black keys as sharps (#). So, if they're sharps (#), then, our keyboard keys should be twelve:
C
C#
D
D#
E
F
F#
G
G#
A
A#, and
B.
Why are the black keys known as sharps here? In fact, what is a sharp on the keyboard?
A sharp (#) simply means, a note raised. So,
C# means, C raised;
D# means, D raised;
F# means, F raised; and so on.
But, hold on! Those black keys can as well be referred to as flats (b). How? Why?
A flat (b) is a note reduced. So, if you reduce a C by a semitone, you get a Cb.
I often tell my keyboard students that, if you're looking at a keyboard from the left to the right, the blacks are sharps (#) ; but, if you're coming from the right to the left, the blacks become flats(b).
