Let it C
This is a good starter strumming tune, even though the recording is piano.
Make the connections. Sing the words [just to make sure: change the ‘C’ to ‘Be’ in Let it ‘C’], or just the melody in la-la-la.
Strum along to the recording.
We first played modes (calling them modes - all scales are modes) in Adding Tones to Em/G & Am/C. There, we added tones to a scale to create other types. In this session, we will use an existing scale that we know, C Major, and derive other scales from the tone group. There are 7 tones in a Major scale, therefore, we will have 7 modes. Each tone of the scale can be a 'starting point'. As previously discussed, modes are tone groups, aka scales. They are scales with special names. Scales which produce specific types of sonic 'impressions'. One way to understand/play modes is to use a scale that we know, such as the C Major scale. Then, play the scale using the different tones in the scale as ‘starting points’. This is called derivative - we are deriving scales from a scale. The way we did it before was to use a scale, such as the pentatonic, and treat it as a shell by adding tones to fill in the 'gaps'. Even another is to use formulas. We can modify a Major scale to create modes and their formulas [parallel]. We can also have a mode, created by whatever means [synthetic, etc.] and understand it by how it differs from its own Major scale. This will also produce a formula. Finally, we can also divide an octave any way which we choose → create our own modes. If modes we create aren't previously named modes, we typically call them synthetic modes [scales we synthesized].
So once we have some experience with the shapes & understand how they work, we can use them to create other chords by modifying the CAGED shapes. We can use formulas, or just experiment. Example formula: minor is R-♭3-5. From a Major chord, we flat (lower, one fret) the 3rd of the chord (wherever it appears). For the E form, the 3rd is the 1 fret on string 3. To create Em, we lower the fretted tone to the open string (G is the flat 3 of E). When we do this, we have Em. This is one way to figure out truckloads of chords.
These Drop D power chords can be played as a 3 string bar chord (string 6-5-4) using the index, the 2, the 2 & 3, the 3, or the thumb over the top of the board. For teaching groups, using the thumb is one of the fastest ways to get results.
