Hey, I'm doing a informative presentation on guitar scales in my communications class, and I need someone to look over my outline to make sure i'm not missing anything important. Also, do you think this is too advanced a concept to try to explain to people who don't know anything about guitars? I'm not sure if this is the right place to post this buy any help is appreciated, thanks!

Musical Scales on the Guitar Presentation Outline
Purpose Statement: To inform my audience about musical scales using the guitar.
Thesis Statement: Musical scales are used on the guitar to create music.
Introduction: Musical scales are used on many different instruments to create music. I will be focusing on the guitar because it will be much easier to explain the concepts on that instrument. There are many different types of musical scales used to create music; different types of scales are more common in different genres of music.
Transition: We will now discuss what exactly musical scales are.
Body
Main Point 1: Musical scales are made of a series of pitches.
1. Musical scales progress in either a half step or whole step. A step is the term for the space between pitches. Musical scales progress in either a half-step or a whole step. For example an E note and E# note are only a half-step apart while an E note and C note are one whole step apart. On the guitar, every fret is a half-step away from the previous fret.

2. Musical scales are classified by their patterns. An example of a pattern would be two whole steps, than one half steps, than three whole steps, than one half steps.

3. The Keys by which musical scales are named come from the pitch a musical scale starts and ends on. The note a scale starts on is the same as the note that the scale ends on, except the note the scale ends on is 1 octave higher. For example, an E minor pentatonic scale starts and ends on an E note.

Main Point 2: There are many different types of musical scales classified by different types of patterns.
1. Every musical scale is either a major or minor scale. A major scale generally sounds happy while a minor scale generally sounds sad. Most of the time fast songs are in major keys, while ballads are mostly in minor keys. The notes in these scales follow a pattern of whole steps and half-steps. The major scale starts at the key note, than follows the pattern of WWHWWWH. The natural minor scale follows the pattern of WHWWHWW.

2. Chromatic scales are scales that follow a pattern of only half-steps. Pentatonic scales are five note scales that are either major or minor.

3. Pentatonic scales are either major or minor with a key note. For example an E major pentatonic scale is basically an E major scale without the 4th or 7th notes. An E minor pentatonic scale is basically an E minor scale without the 2nd and 6th note.

Main Point 3: Guitar scales are used to create music; different scales are more popular in different genres of music.
1. Guitar scales are used to either construct guitar chords or solos.

2. Guitar scales can be used to improvise, or come up with progressions on the spot.

3. The Pentatonic scale is very popular in rock music, especially the minor pentatonic. For example, Jimi Hendrix’s song, “Voodoo Child (Slight Return)” is based on the E minor pentatonic scale. Also, Led Zeppelin’s, “Stairway to Heaven” is based off of the A minor pentatonic scale. Country music is primarily based off of the major scale.

Conclusion: In conclusion, musical scales can be used on the guitar to create different melodies.
