Key Signatures - Minor Keys

KEY SIGNATURES - MINOR SCALES

“What do you get when you drop a piano down a mine shaft?”

Answer: A FLAT MINOR

RELATIVE SCALES are a minor third apart - Major scale above, minor scale below.  Here are the steps:

• Work out the major key signature.
• Work a third down through the major scale from the tonic [to the sixth note or submediant], and this will give you the keynote [or tonic] of the relative minor scale.
• Remember that the seventh note [second last] of the minor scale is raised a semitone.
• If you know the minor keynote, you will need to do the opposite to find the relative major - go a minor third higher - and then work out the key signature.

Key Signatures - Major Keys

KEY SIGNATURES: MAJOR KEYS - “The only sentence you will ever need to learn”

Key signatures will ALWAYS be identical on both staves.  Yes, it is possible for them to be different - its called "polytonality" [literally "many key signatures"] or "bitonality [literally "two key signatures"] - we’ll look at that later.  You will need to be able to read them and write them in either clef, remembering that the letter names have different positions on each.

Learn this sentence:

Father

Charles

Goes

Down

And

Ends

Battle

Read downwards it is the order of sharps, so the key signature that has one sharp WILL ALWAYS BE an f sharp.  Four sharps would be f, c, g & d.  Identifying the key note [the tonic or first note of the scale] of the MAJOR SCALE is easy from a key signature.  Remember this: the LAST SHARP in the key signature is ALWAYS the SEVENTH NOTE of the scale [the one before the key note or tonic].  So, for example, the key signature of f sharp: f sharp would be the seventh note, going one step up gives you a G = G major.  The four sharp signature given above, the last sharp is d ["Father Charles Goes Down]", going one step up to E = E major.  This is true of ALL key signatures containing sharps.

For flat key signatures, go back to the sentence and read it BACKWARDS:

Battle

Ends

And

Down

Goes

Charles'

Father

This is the order of flats.  So the key signature with two flats will be b flat and e flat.  Five flats would be b, e, a, d, g.  Identifying the key note is also easy for flats, just different.  The SECOND LAST FLAT IS the key note. So, for two flats, the second last flat is b flat = B flat major.  For the five flat key signature above, the second last one is D flat = D flat major.  This is true of ALL key signatures containing flats [almost - see below].

Learning these, you can work out every major key that exists, with two exceptions, which you must remember:

[a] C major has no sharps or flats, so you can't apply either rule to it.

[b] F major has only one flat, so it doesn’t have a second last flat.  However notice that its last [only] flat is the fourth note of the scale, and in all the other flat key signatures the LAST flat will be the fourth note of the scale too.  You could work them all out that way - if you do, remember "SHARP SEVENTH note, FLAT FOURTH note".

You can also apply those rules in reverse to work out a key signature from any given tonic note.  What would the key signatures of the scales commencing on these notes be:

D major

B major

B flat major

A major

A flat major

E flat major

Finally, I've said "MAJOR" scales here.  MINOR keys are different, in that you've got to do all this, but there's another step involved - we'll worry about that another time.

Scale Degree Numbers, Technical Terms and the Pentatonic Scale

NOTES:

* The following table should be read from bottom to top, just like a scale.

* Scale degree number “8” is called “1”, because they are the same note, an octave apart.

Number	Technical name	Major solfa	Minor [harmonic] solfa
1	tonic	doh	la
7	leading note	ti	se
6	submediant	la	fa
5	dominant	soh	me
4	subdominant	fa	ray
3	mediant	me	doh
2	supertonic	ray	ti
1	tonic	doh	la

WE also looked at THE [anhemitonic] PENTATONIC SCALE

Pentatonic = “5 note scale”

Anhemitonic = “without semitones”

1. Write the following notes of the C major scale on the staff:

tonic, supertonic, mediant, dominant, submediant, tonic.

2. Write the appropriate solfa names [major] under each of the notes.

3. Play and / or sing it through.

Writing Scales

There are a number of scales you can be asked to write.  The major scale is the first that you are likely to meet, followed closely by the harmonic minor scale.

How many letters does the musical alphabet have in it?  SEVEN

At first, you will have to write scales over one octave.  The basic structure of a scale is very easy to set out.  They all use every letter names once only, with the exception of the first note, which is given one extra appearance (once at the beginning and once at the end).  This note is called the “tonic” or “key note”.

WRITING SCALES OVER TWO OCTAVES.  A one octave has eight notes in it.  So, how many notes does a two octave scale have?  FIFTEEN

WHY?  A one octave scale contains every note of the musical alphabet played ONCE, with one exception: the key note, which gets ONE extra playing - at the top as well as the bottom.  A two octave scale contains every note of the musical alphabet TWICE, with one exception: the key note which gets ONE extra playing, not two extra playings.

Syllables, accent and rhythm in verse

We speak with a natural rhythm, accenting certain syllables over others.  Poetry takes advantage of these natural stresses to create a regular pulse when it is read. 

1. Find the words which contain more than one syllable in the verses below and write them down next to the verse, indicating the division between syllables with a hyphen (“-”):

• Look for prefixes and suffixes, which easily separate from the rest of the word.
• Where there are consecutive consonants, it is usual to split the word between the consonants, especially double letters.  However, consonant blends (“-ph-”, “-ch-”) should remain intact.
• Splitting a syllable immediately after a vowel implies that the vowel is a long one, and you need to decide whether that is appropriate given its usual pronunciation.

My Love is like a red, red rose

That's newly sprung in June; 

My Love is like the melody

That's sweetly play'd in tune.

(Robert Burns)

Birds of a feather flock together,

And so will pigs and swine;

Rats and mice will have their choice,

And so will I have mine.

(from Mother Goose)

Dear friends, we surely all agree

There's almost nothing worse to see

Than some repulsive little bum

Who's always chewing chewing gum.

(Roald Dahl)

Old Deuteronomy's lived a long time 

He's a cat who has lived many lives in succession 

He was famous in proverb and famous in rhyme 

A long while before Queen Victoria's accession.

(T S Eliot)

2. Find the accented syllables in these words.  Read each of these words aloud or quietly to yourself.  Notice how one syllable will stand out from the others.  Mark that syllable by underlining it.  If you’re not sure where the accent should go, experiment by stressing each syllable in turn, until you find the one that makes the most sense.

3. Choose one of the stanzas above, and place a vertical line BEFORE the accented syllables.

You will probably have more than one accent per line.  The first accent is not always on the first syllable.  If an accent falls within a multi-syllabic word, it will always be on strong syllable.  If a word is long enough, it may get a number of accents (“Supercalifragilisticexpialidocious”).

[HINT: How many marks are assigned to this question? 7 marks would indicate that the examiner will expect seven accents to be marked.  If you’ve got more or less, you’re probably wrong.]

WRITING RHYTHMS TO VERSE

This part of the exam is called, “Creative”, which means that there is more than one right answer - within limits!  Those vertical lines you marked in your verse represent bar lines in music, and if you’ve done this correctly, you’ve grouped the syllables into roughly equal groups.  This may suggest one or more appropriate time signatures to you.

Choose a time signature for your verse.

Now, write a rhythm, using ONE note per syllable.  Make sure you adhere to your bar lines.  It should reflect a natural way of saying these words, although as you get more confident doing this you could incorporate some more unusual rhythms to add an element of surprise.

Finally, you need to present the words and rhythm together.  The words will be split into syllables wherever necessary, using hyphens.  When you write the rhythm out, make sure you give yourself lots of space between notes so you can place each syllable directly underneath the note that belongs to it.

Time Signatures and Note Groupings

Time Signatures

Time signatures are classified using two words:

Simple or Compound
and
Duple, Triple or Quadruple

Simple / Compound refers to the beats which make up the bar - if the beat is a note without a dot it is "simple", if it is dotted it is "compound" (that is, it is NOT SIMPLE, it is complicated).  In actual fact, "compound" time refers to a time signature in which the beat is not divided equally into halves, it is divided in to thirds.

Duple / Triple / Quadruple refers to the number of beats (this is the easy bit): 3 beats is "duple", three beats is "triple", and four beats is "quadruple".

Note Groupings

The purpose of grouping notes and rests is to simplify the reading of music for the player.

Some fundamentals:

• You can fill a whole bar with a single note or rest.
• In most cases, any note that includes the first beat is OK (*see the end of the activity sheet).
• You can group beats 1 & 2 together, and beats 3 & 4 together (where they exist),
• BUT YOU CANNOT group beats 2 & 3 together.
• You can group the first and second parts of a beat together,
• BUT YOU CANNOT group the second and third parts of a beat together.

EXCEPTIONS - For when applying the usual rules makes it look more complicated (remember, the aim is simplicity for the reader).

If you’re not sure, ... GROUP TO SINGLE BEATS.

In an exam, you might be asked to:

• Complete a bar with rests (do this for the first bar in each line below)
• Complete a bar with quavers correctly grouped (do this for the second bar in each line below
• Complete a bar with semiquavers correctly grouped
• Complete a bar with notes and rests (do this for the last bar in each line below)
• Identify correct and incorrect groupings
• Identify time signatures from groupings
• Correct groupings
