Triads are simple Chords. Chords are similar to scales, because they sound pleasant, and share a relationship between notes (hopefully a loving one). These relationships become complex whenever Chords change, and musicians must create melodies based upon Chords.
To simplify Chord reading, we practice which sharps and flats are in scales. Then improvisation (creating melodic phrases) flows freely. It's inspiring to create beautiful art, as our instrument or voice skills improve.
Wow, we're getting deeper: Remember Triads are simple Chords. Without sharps and flats, we don't know how triads are supposed to sound on our instrument. Since I'm all about Sound, let's get down to the proper keys.
C Major has no flats or sharps:
Starting on the root of the scale, C:
This makes a triad, with every note natural.
The next triad starts with E, the 3rd scale step from C (CEG). First find E's key. Stay with me now :)
E Major contains sharps, and one half step down from E is D#. Following the Order of Sharps, we count up to D#, as follows:
Four sharps are in the key of E. When improvising over the E triad chord, we must sharp every F,C,G,D:
The last triad starts on G, the 5th note of the C triad (CEG). Find G's key by going down a half step, to F#. Then follow the order of the sharps to F# (Fat, lol). The G Major triad is:
When playing melodies over G triad (chord), sharp every F. Begin finding a scale's key when a triad appears, in order to improvise the correct notes.
To bring these triads together:
Triad branches may develop from the last note of each triad, changing chords:
See how the root note changes?
Let's put theory into practice.
Little snippets of phrases, or themes, in music sound good, or catchy, when played over chords. They're like parts of melodies that I call Licks.
Remember songs like, "Theme from the Twilight Zone", or, Beethoven's "Symphony No. 9", or, "Santa Clause is Coming to Town"? Each contain parts of melodies that people remember later.
"This method beats plodding through scales, because we learn Keys by creating music."
"Santa Clause is Coming to Town" has a part that goes, "better watch out... better not cry". It's just 4 notes that are echoed with 4 more notes. These are the same consecutive notes in a major scale, the 3rd, 4th, and 5th notes (repeat 5th note), echoed by the 6th, 7th, and 8th (repeat 8th) notes. This analysis of song snippets, or licks, allows us to find in what scale they belong, and in which key.
In Beethoven's Ninth Symphony, we may remember the beginning, which is 3 of the same notes, followed by a long note, which is a 3rd step down from the first three. In this phrase, as well as others, we can play them over triads or chords, and they'll sound perfect if played in that triad's Key.
And stringing along many phrases or licks, keeping the notes in the key of the triads, we will be improvising, or creating our own personal melody, backed by chords.
Imagine a band is playing chords behind our solo, and we're playing the licks we know. When the chord suddenly changes, we must play different notes for the same lick. "What, you mean a phrase can be played in any key?" Yes, if we first name the Key of the chord, then flat or sharp the proper notes for our lick.
We might write down different triads or keys, and try to change the lick quickly into each. This method beats plodding through scales, because we learn Keys by creating music. Many of the phrases or licks are formed by breaking a Major Scale into pieces that have diverse rhythms - which leads to our next subject:
We've entered the fun zone of music.
Rhythm makes notes' duration (length of sound) long or short. We know the difference between a long or short note, and we remember snippets of phrases from various songs, so we may understand how rhythm works to divide up a note's length. So, sound has duration, but what duration is between the sound? It's silence that's called Rests.
In other words, Rhythm is sound and silence of different lengths; or Notes and Rests of different durations. Without looking at sheet music, we can analyze the sound duration from radio, internet, or wherever there's music.
Why doesn't music sound random, like other noises? Because the sounds are setup to the Keys. Likewise, note phrases are divided into pieces that are catchy, and sometimes symmetrical in their divisions. The durations for each note or rest are in equal complementary parts.
We've heard pieces of sound, but what's important is how phrases' notes are put together with different lengths or durations, to sound catchy or pleasing. Beginning musicians often ignore rhythm, because they are concentrating on getting the sound to mesh properly with the keys, or chords. But no one wants to get up and move to a boring sound. We've gotta punch it up with rhythm!
So, play some notes, making some shorter and louder for emphasis. The phrase's feel changes. Our minds may get so stimulated by a phrase, that another pops into being, to continue the line of melody. That's true Improvisation, when inspiration springs from sound.
Let's look further into the divisions of sound: Music is about symmetry, which comes from equal divisions of notes. These divisions are based on a pattern, usually 2, 3, or 4. The brain may only be able to digest little pieces at a time, and more than 4 gets complicated.
So, dividing a sound into 4 equal parts, makes 4 equal parts of silence, or rests, between the sounds (counting the rest after the last sound).
We may now say we have 4 sounds, and call them Beats. Each Beat can be a different note, but we are keeping the duration (length) of the notes equal. So, 2 of those notes are half of the 4 beats as a whole.
And 1 of those notes is a quarter of the whole amount (4).
Likewise, 2 rests are half of the 4 rests, or whole. And 1 rest is one quarter of all the rests (4). This equality of 4 notes and rests, sounds good in rock music.
Moreover, if we divide in 3's, then we have 3 notes, and 3 rests.
This equality of 3 notes and rests sounds good in musicals, old dances like waltzes, and some Latin music. You'll know if the music has a division of 4 or 3, just by listening for when the phrases end.
Confusion in written music happens, since the same written note appears for every type of division, 2, 3, or 4. We simultaneously must do the math of the rhythm, and determine which tone to produce. This mix of sound and duration sometimes distracts new musicians, so they exclude one or the other.
Combining a tone's pitch (high and low), and length is easier when we think of a melody in the midst of a background beat. Melodies speak to us through emphasized notes and changing pitch, just as in conversation. Even the pauses (rests) suggest rhythm and meaning.
