UNIT 3:CHORDS, DYNAMICS AND TEMPO
Key unit competence:
Be able to compose songs in major and minor mode and sing them respecting
dynamics and tempo.
Introductory activity:
1. In group sing any song you know in ten diff erent ways indicated below,
then discuss:
a. Moderate speed
b. Slowly
c. Very slowly
d. Quickly
e. Very quickly
f. In a low voice
g. In a middle voice
h. In a high voice.
i. In a very high voice
2. Below we have three notes (C-E-G).
a. In your group, you are going to play and sing the three notes
simultaneously.
b. Put a fl at on E (=Eb) and again play and sing simultaneously.
c. Now compare the two sounds you get after singing the two sections. i.e.
(C, E, G and C, Eb, G).
A triad is a chord consisting of a root tone, the tone two degrees higher, and the
tone five degrees higher in a given scale sounded simultaneously; a bottom note is
known as root, a middle note is a 3rd and a top note is a 5th.
How to make a triad?
Suppose the first note start from C. Write the first note (root) at the bottom and count
up 3 to get the next note a 3rd (include the starting note when you are counting)
(in our example, 3rd notes up from C is E). Now start again at the bottom note and this
time count up 5 (5th notes up from C is G). So, to build a triad on C we have used the
notes C-E-G.
Below is how a triad looks like on musical staff and keyboard.
Suppose the first note starts on F
So the root is F, the next note is A and the last note is C. So to build a triad whose
root is F we have used the notes F-A-C. Below is how it looks like on the staff and
keyboard.
3.1.1. Minor and major triads
a. Major Triad
As we have seen a major triad is created by taking a root note and combining it
with a major third and a perfect fifth. Thus a major triad can also be described as
a major third interval (2 tones) with a minor third interval (1tone and semi-tone) on
top.
If we take C as the fi rst note (a root) we shall have the following major triad.
3.1.2.Diminished and augmented triads
Apart from major and minor triads, we have also two other triads qualities which are
diminished and augmented triads. A diminished triad is built with a m3 and a dm
5 above the root.
3.1.3. Inversion of triads
Inverting triad is writing its note in other ways. The examples we have seen above
are written in root position.
Consider the examples below C as the fi rst note (the root).
A chord is a group of three, four or more notes played simultaneously. There are
diff erent types of chords. The most common chords are triads. The common used
chords are major and minor chords.
3.3.1. Major chords
A major chord consists of a root, a major third and a perfect fifth. For example, the
C Major chord includes the note C-E-G. The E is a major third above the C; the G is a
perfect fi fth above the C. It is founded as Major triad.
Below is how to build perfect major chords on every note of the scale
3.3.2. Minor chords
The main difference between a major chord and a minor chord is the third that
modifies the number of tones and semi-tones.
In group of four discuss what could happen on third when making minor chord.
Below we have a minor triad chord.
Something to remember: the minor chord is the same as the major with the same
letter name except the 3rd degree is fl atted in the minor chord.
3.3. Diatonic chords
Learning Activity 3.3.
Consider the following scales:
3. CDEF#GABC
4. CDEF#GABC
5. GABC#D#EFG
6. GABC#D#EFG
a . Identify the notes that do not belong to the above fi ve diatonic scales,
b. Build the triads based on
1. C tonic.
2. G tonic.
Diatonic chords are chords whose notes are made from the note of the particular
scale, being minor or major. It means all notes of these chords are found inside that
particular scale; no notes outside the scale.
3.3.1. Major Key diatonic triads/chords
Taking C major as an example, we can show the seven types of diatonic triads that
occur on each degree of major scale.
Use of roman numerals
The Roman numeral indicates the scale degree of the chord root; e.g.: (I, ii, iii, IV V,
vi, viio)
Triad/ Chord quality are indicated as follows:
Major is upper case: I, IV, V
Minor is lower case: ii, iii, vi
Diminished is lower case with an added º: vii°
Remember that, this pattern I, IV, V (major chords), ii, iii, vi (minor chords) and viio
(diminished chord) is common to all major keys.
3.3.2. Minor key diatonic triads
Taking A minor natural as an example, we can show the seven types of diatonic
triads that occur on each degree of the minor scale.
Use of roman numerals
The Roman numeral indicates the scale degree of the chord root e.g.: (i, iio,III,iv,v,VI,
VII).
Triad/ Chord quality are indicated as follows:
- Minor is lower case: i, iv, v
- Major is upper case: III, VI, VII
- Diminished is lower case with an added º: ii°
Notice that these are the same diatonic chords of C Major. Only the Roman numerals
and their qualities have shifted over by the notes (or six depending on which
way you go) to accommodate the relative minor key of A.
Remember that, this pattern i, iv, v (minor chords) III, VI, VII (major chords) and iio
(diminished chord) is common to all natural minor keys.
Application activity 3.3 (a)
1. In C major key which triads are minor?
2. In A minor key which triads are major?
3. Using notes of the C major scale, build chords on a very scale degree.
3.3.3. Primary chords
Primary chords or I IV V chords are the three most used chords.
For example, in the key of C major the primary chords are:
C (I), F (IV) and G (V).
In D major, the primary chords are:
D (I), G (IV) and A (V).
Major key diatonic chord names are:
- i chord = Tonic
- ii chord = Supertonic
- iii chord = Mediant
- iv chord = Subdominant
- v chord = Dominant
- vi chord = Submediant
- vii chord = Leading Tone
So the primary chords are:
- i =Tonic
3.4. Dynamics and tempo
Learning activity 3.4
1. In a group of fi ve learners choose your favorite song and perform it in the
following three ways:
a. slowly
b. moderate speed
c. quickly
2. Perform again the same song in the following three ways:
a. Low voice
b. Middle voice
c. High voice
3. Appreciate the diff erent ways of performances
Both dynamics and tempo direct the performer or conductor during music
performance to which speed or loudness a piece of music is to be performed.
1. Dynamics
The following combinations are possible, going from softest to loudest:
fp=Forte piano= begin the note loud, but drop it to soft immediately.
sf/sfz= sforzando= forced, accented, sudden accent on a single note or chord.
sfp=sforzando piano=sudden accent followed immediately by soft.
fp=forte piano= loud followed immediately by soft.
Words used to indicate changes in dynamics. These are qualifi ed terms used to
indicate the mood, degree intensity or style.
- Fortissimo piano = very loud and then immediately soft.
- Marcato = stressed, pronounced.
- Pianoforte= soft and then immediately strong.
- Smorzando=dying away.
- Agitato= agitated.
- Animato=animated.
- Dolce= sweetly.
- Expressive=expressively.
- Energico= energetically.
Articulation
In music, articulation refers to the musical direction performance technique which
aff ects the transition or continuity on a single note, or, sometimes—they (articulations)
mark the strength of individual notes. They can be placed above or below
the notes.
Below are some of the articulations we use in music
Slur is a symbol indicating that two or more notes it embraces are to be played or
sung without separation. These notes are played in legato style.
Tempo can also be indicated by using the Italian words to approximate the speed.
Grave= extremely slow and solemn (20–40 BPM)
Largo= slow (40–60 BPM)
Lento = slow the same as Largo. (40–60 BPM)
Larghetto =a little faster than largo and Lento (60–66 BPM)
Adagio = Moderately slow (literally, "at ease") (66–76 BPM)
Andante=at a walking pace, moving along/walking tempo (76–108 BPM)
Andantino=slightly faster than andante
Moderato= moderate pace(108–120 BPM)
Allegretto=moderately fast/slower than allegro (but less so than allegro)
Allegro=fast, quickly and bright (120–168 BPM)
Vivace= fast/quickly and lively (≈140 BPM) (quicker than allegro)
Vivacissimo =very fast and lively
Allegrissimo=very fast
Presto=very fast (168–200BPM)
Prestissimo =extremely fast (more than 200 BPM)
Additional terms
A piecere= (also known as adlibitum in latin) the performer may take liberties with
regard to tempo and rhythm; literary at pleasure.
Gradual change in tempo
Often a tempo will change gradually. Gradual accelerations or decelerations in
tempo are indicated by:
Terms used to indicate simultaneous reduction of speed (tempo) and volume.
Mor. Morendo=dying away
Cal. Calando =decreasing tone and speed
Smorz. Smorzando=dying away
Incalzando=increasing tone and speed
Application activity 3.4. (a)
1. Draw lines connecting each musical term or symbol to its correct
defi nition. First word is done for you.
2. Solfa and sing respecting dynamics and tempo
3. Repeat signs
Repeat signs are used to diorect the performer to which section of the music should
be repeated.
How to follow repeat signs?
Repeat Sign
Two dots before a double bar form a repeat sign. If a repeat sign occurs at the end
of the piece, it indicates that you should repeat the entire piece of music once from
the beginning up to the end.
Inverted repeat
To play the inverted repeat, you play to the original repeat, then you go back to the
inverted repeat and play/sing to the end. In the example below the inverted repeat
sign means that you should skip the fi rst measure when you repeat the piece.
Alternate Endings (1st and 2nd ending)
A bracket and number are used to show the performer that there are multiple endings
for a piece of music. You should play/sing though the fi rst ending, and then
return to the beginning. Then play/sing through the piece again skipping the fi rst
ending; play/sing the second ending until the end. Third and higher ending are
also possible.
Da Capo (D.C.)
Da Capo (abbreviated D.C.) means go back to the beginning of the piece and
repeat.
To perform a D.C. you play/sing until you reach to D.C. then go back to the
beginning then you play/sing from there until the end of music.
Dacapo al Coda (D.C. al Coda)
To perform ‘Dacapo al Coda (D.C. al Coda)’ play/sing until you reach D.C. al Coda
, go back to the beginning and play to the Coda sign; then skip, and play the
CODA (a short ending section).
ber of measures at the end of the piece
a. Writing triads in four parts
There are four main voice types:
- The top voice is soprano (high women’s voice)
- The next lowest voice is alto (low women’s voice)
- Then comes the third voice, tenor (high men’s voice)
- The lowest is bass ( low men voice)
The term voice and part are used interchangeably to help distinguish the voices
when four parts are written:
The soprano and alto are written on the top staff and tenor and bass are written on
the bottom staff . Stems for soprano and tenor notes go up. And stem for alto and
bass notes go down.
Consider the example below:
Plagal cadence
The progression of plagal cadence is IV to I in major keys, or its equivalent iv to i
in minor keys. It is also known as the Amen Cadence because of its appearance in
church hymns ending with Amen.
Plagal cadence on the staff
Half cadence
Half cadence progresses as follows: I–V or IV to V. This cadence appears mostly in the
middle of the song
Example on the staff
Advice to the beginner in composition
Don’t repeat the same note too often
send your song on the tonic or authentic cadence
start by composing short melodies
start with a one voice song and then four voices
avoid long leap
often use the root of the chord in bass
The whole process of mixing notes in four parts is known as harmonization
