Music Theory – Things To Learn

Here is a brief overview of the various elements of music theory; some key topics that you will need to learn.

Notes & Pitches
Notes on Piano
Sound is nothing but vibrations produced in air. The frequency of the vibration is known as a Pitch. The greater the frequency, the higher sounding the pitch!

The various pitches are then named as musical notes. It is these musical notes that we need to know and recognize to be able to play any musical instrument.

The seven musical notes are: A B C D E F G.
Besides these seven notes, there are accidentals which sharpen or flatten these seven basic notes.

Melody is the tune of any song or piece… the part that we usually hum of our favorite songs. It is a series of notes that is played in succession.

To create a piece, a composer would normally start using some melody notes and then build upon it or take some chord progression and then build upon it.

To create a musical piece/melody, the composer would use elements like: the musical notes, their durations, dynamics, and selection of various musical instruments.

Scales, Modes
Piano Scales The various notes can be arranged into different scales and modes. A scale is nothing but the relationship of the various pitches in some particular order.

The different scales can be played in various keys, 12 different keys to be precise.

Composers use various keys to see how it affects the overall song. If played on any musical instrument, a song in scale C may sound similar to what it may sound on scale G… but when you here the complete arrangement of the song, it may sound better in certain scales.

Rhythm means arranging the musical notes in time. This is where you will need to learn about time signatures.

The time signature or meter basically maintains a regular pulse throughout the song; it tells you what beat you need to maintain for your song.

I am sure you would recognize a song which has a waltz rhythm – the typical 1 2 3, 1 2 3 beat. Besides the waltz, the other common rhythm is the 4/4 time. You will find most of the songs based on these rhythms.

Harmony (chord progressions)
Here you will need to learn how to move from one chord to the other. The different chords in a scale are identified using Roman Numerals such as I, II, III, IV, V, VI and VII.

Chord progression means moving from one chord to the other to give the desired effect.

Some of the common chord progressions that are used in musical pieces/songs:
V – I
II – V – I
IV – V – I

Piano Chords
