Episode 9: Understanding Intervals Part 2

(pic from icawa)
Hello and welcome back everyone! Now as I left off with this series, we talked about the basic intervals; Major Minor and Diminished. Now I'm going to add two more intervals to the set that you know and a a couple of special cases you may have heard of. As always, if this interests you then don't be afraid to add to the friend pages on Twitter and Facebook!

Now to review what we talked about last week, we went over the intervals and how to tell them apart from one to the other. As I showed with the chart at the bottom of the post, it is nothing more than following the half steps between the notes. So in case it was a little confusing that way, here is another way of thinking about it.

Original Chart:


       Minor         Major        Perfect
1                                                    0
2        1                 2
3        3                 4
4                                                    5
5                                                    7
6        8                 9
7        10              11
8                            12

Simpler Chart:

       Minor         Major        Perfect
1                                                    0
2        H                 W
3     W+H             2W
4                                                  2W+H
5                                                  3W+H
6       4W             4W+H
7       5W             5W+H
8                            6W

H= Half Step

W= Whole step (2 Half Steps)

Now the new material I wanted to mention to you is a Diminished (o) interval and Augmented (+) interval. A diminished interval is an a half step below a minor interval and an augmented in a half step above a major interval. So for example we have a G-Bb which is a Minor 3rd (G-Ab-A-Bb), then a step below that is a G-Bbb (B double flat). Another example would be an D-Fb because a D-F is a minor 3rd, but lowering it down a half step makes it a diminished interval. Another way to look at the same interval is a D#-F. D-F in a minor 3rd, but raising the base note still closes the gap in between the notes. Now looking at augmented intervals, let's take a G-B which is a major 3rd. If you add a half step to the B you have a G-B# which makes it an augmented interval. Another way to see it is a Gb-B would be an augmented 3rd. Don't let the enharmonic spelling throw your answers off. A B# might sound like a C, and is an enharmonic spelling of C, if the note they write is a B then the notes around it must fit the occasion. Another example of augmented intervals is a G-C#. G-C is a perfect 4th, however with the addition of the sharp we have an Augmented 4th and the first of our special conditions.

The example mentioned above (G-C#) is an augmented 4th, but it is also a tritone. A Tritone is the a series of notes that are the exact middle of our 12 tone interval system. G-C# is 6 half steps from either tonic and give a very dissonant and very identifiable sound to music. A tritone consists of either an augmented 4th or a diminished 5th. Both are in the middle of our scale system.

Another way that I think makes learning intervals easier is the use of inversions. An Inversion is the process of moving one note an octave higher or lower to find an interval. The rule of inversions is if an interval is major before the inversion then the inverted interval is minor. The reverse is true as well, if an interval is minor then inverting it will result in a major interval. So a M6 would invert to a m3 and a m7 would invert to a M2. Perfect intervals always invert to perfect (P4 inverts to a P5, and PU inverts to a P8). Then Augmented always inverts to Diminished. That's why there are two notes that make up the tritone, augmented 4th and diminished 5th. 

Episode Recap 1: Episodes 1-5 Part 1

Hello and welcome back! Now before I begin the recap let's go over a few things. 1st off, you may have noticed the button above me. Finances are really low, especially if you want more reviews so please donate anything you feel comfortable donating to me. I am wanting to do more reviews and if you want to see more, then any money is good money! With that said, I promise I WILL NOT go crazy with the button! The only time I will post it is on general recaps (like such), and reviews. I want to provide everyone with a few service to learn music theory, tricks from professionals, and reviews so you aren't wasting your money on pointless or terrible stuff for your instruments (and yes, I have used some terrible stuff, and amazing stuff so I know what's good and what's not).

With that out of the way, I bet you're wondering "What's an 'Episode Recap'?". I feel after so many episodes on all my topics, I will post one giant summery for you on what is in that section. For today, this episode recap is on episodes 1-5, which are:

-Episode 1: Musical Alphabet and Note Values

-Episode 2: Sharps and Flats

-Episode 3: Treble and Bass Clef

-Episode 4: Defining the Signatures

-Episode 5: Dynamic Contrast

Now how this is going to work is like a review over the selections, and explain some harder to explain things.

Episode 1:

This was a presentation-Only entry so most people didn't read this entry, so I will count this as the actual lesson. There are two main elements when reading music: a Note and a Tone. A note is the visual representation of a sound (♪). The actual sound that goes with it is the tone. We could say that the note is an A, or a C but we don't see that when we are watching a group play: We hear the tones of the chord(s) the person or people playing make but we don't see the (♪) in front of us unless you brought sheet music with you.

When you link them together in any pattern going up or down until you repeat the first note, you get a Scale. There is no simple number of notes in a scale, because there are so many different types of scales. However, there is a "Western" standard of scales, which has 8 tones in a repeating pattern. I will discuss this more later on in the episode review. 

Now we have to discuss the Musical Alphabet. This is the way musicians learn their notes, and it is always repeating: A, B, C, D, E, F, G. 

A standard Octave or simply the "Western" style of 8 note scales, is the repetition of one note. For example take a C scale. If we wrote it out we would have C, D, E, F, G, A, B, C. The bold C is an octave higher than the one we started on. This works out on the entire musical alphabet.

Now, we talk about basic note values. They work the same was as fractions, which is they break down and are seen as fractions, like for example ♪ is an eighth note while ♫ is two eighth notes or a quarter note. The way the notes flow is demonstrated in the following picture:

The top note is a whole note, and it breaks down into two half notes. each half note breaks down into two quarter notes and so on all the way down the line. This is the proper way to subdivide notes. Now we must figure out how this fits into a staff. A Staff is a bar with 5 lines and 4 spaces that fit together and are split to make Measures. This will be further explained in a later chapter.

Episode 2:

Going back to notes on a staff, you can have either Sharps, Flats, or Naturals. Naturals are notes that haven't been altered and these are the white keys on a piano. Then if you take that note and go up a half step (going from a white key UP to a black key) your going from a natural to a sharp. When you go down a half step (going from a white key DOWN to a black key) your going from a natural to a flat. *Editor's Note* I just realized there was a glitch in the episode, and I fixed it so it's legible.

Episode 3:

There are 2 major clefts to playing most instruments. You have Treble, or the G cleft, which is the higher side and you have the Bass, or the F cleft, uses the lower side. Back to the discussion on scales. The "western" or non-asian countries use a standard for scales which goes with the "standard" of 8 notes that repeat at the base note but at a distance of an octave. For example: C Major is C, D, E, F, G, A, B, C.

Episode 10: Scale Theory

Hello and welcome back!

Sorry I haven't posted in the actual episodes in a while, but college seems to keep me busy no matter which way I turn. But today, our lesson is to explain what a scale is and give you some to practice!

First off, we need to figure out how to define a scale. A scale is a series of notes in an ascending or descending pattern. For example, let's start with the note C. There are many different scale involving the letter C but they have to follow some kind of pattern. As I said before there are many different types of scales, but the over all feel is there are two basic scales: a major and a minor. Just like they sound, the major scale sounds brighter than the minor. The whole understanding of scales goes back to understanding intervals, which was the topic of the last two episodes (episode 8 episode 9).

The basic progression of a Major scale is W W H W W W H, where W is a whole step and H is a half step. Now let's apply this to a scale, and since the basis of all music is C let's develop a C major scale. It starts on C, then a whole step up would lead to a D (C#- D), followed by a whole step to an E (D#- E) but then we hit the half step in which we get an F. A whole step to G (F#- G), then an A (G#- A), followed by another whole step to B (A#- B) and then we have our last half step back to C. So a C major scale is C D E F G A B C. Now, let's do another example with F. Start with the note given, and follow the intervals above. So a whole step above would be G, another whole step to A but then we get to the half step which we use Bb. Now we need another whole step to C, another whole step to D a final whole step to E and then the half step back to F. So the scale is F G A Bb C D E F. Ok, let do one last example with G. Follow the guide and you should get G A B C D E F# G. The F# in this example and the Bb in the previous one are ways to indicate a key. F# is the only sharp and the rule of key signatures is take the last sharp and raise it a half step. The trick to flat key signatures is take the second to last flat and that is your key, however the key of F is the only key that doesn't follow this rule. So if we went up to the next flat in the order of sharps and flats, it would be Eb but the key would be Bb.

Now the trick to minor scales is moving the pattern above back two spots. For example, the natural minor of C is A minor, and is played like C but starting on A. The same is true for the other scale above; the natural minor of F is D minor and the natural minor of G is E minor. The pattern is W H W W H W W. A minor would be  A B C D E F G A, D minor would be D E F G A Bb C D, and finally E minor would be E F# G A B C D E.

Episode 5: Dynamic Contrast

Welcome back to the blog, now with a new title and new series that you should take a look at in your free time. However, today's lesson is on dynamics and their importance. Dynamics is the volume of a note or series of a notes. Traditionally, volume is ranged from a Forte (f) to Piano (p). Forte means to play loudly, while piano means to play quietly. The range is controlled by either instantly changing music from being loud to soft and vice versa, or with a Crescendo (<) or a Decrescendo (>), which means going from one dynamic to the other Gradually. You can also write music as a crescendo from a piano to a forte or as a decrescendo from a forte to a piano. Just keep in mind that you need to keep the change within the style that you are playing, like a forte can't blast everyone's eardrums if you are playing a song that just needs to be under another part, but you need to play loud enough to be heard well.

Now, later on in music we move onto and see mf (Mezzo Forte) and mp (Mezzo Piano). Mezzo means to play moderately, or slightly less than (or more than) the dynamic. So for example, a mf would be read as a slightly less than forte, so you play under forte. For mp you should think it is moderately piano, so slightly louder than a piano. Finally, we get to extreme dynamics which are Fortissimo (and above) and Pianissimo (and below). Fortissimo, or ff, is the loudest you can get without making the tone sound bad.

Episode 2: Sharps and Flats

Hello, and welcome back to my blog! The first thing we need to discuss is intervals. An Interval is the distance between two notes. In most cases on a piano, the space between any two white keys or between any two black keys is considered a whole step. Let's take this piano for instance...

Look to the left and you see there is a black key between each white key EXCEPT between B-C and E-F. Those spaces between white keys with a black key in between them are called Whole Steps. The spaces in which there isn't a key in between them, for example B-C or E-F are called Half Steps.

Now, you may be wondering what are the black keys are called. They are called Accidentals. They are listed as a Sharp (#) or Flat (b). If you need to, you can also make the note a Natural but we will discuss that later. All white keys are considered naturals, for example the C's are read as "C Natural", but when you hit the key between C and D, you have a C sharp (C#) and enharmonically a D flat (Db). Enharmonics are notes that are read in different ways. A good way to practice that is going up the octave (from left to right) make everything sharp (C, C#, D, D#, E, etc.) until you get to the next C. Then go back down and say everything with flats (C, B, Bb, A, Ab, G, etc.)
