Triads have 3 notes from the parent diatonic scale:ĭepending on the type of triad, the 3rd and 5th notes can either be natural (not lowered or raised) or flatted (lowered by one or more half tones). ChordsĪcross all keys, guitar chords (often) consist of simple triads. The most common minor guitar keys are Am and Em. The most common major guitar keys are G, C, A and D. However, in Cm, you either need to use a barre chord or place a capo on the 3rd fret and transpose your chord voicings to the key of Am. For example, in the key of C, you can play the root chord ( C major) in open position. Yet, in standard guitar tuning, some keys are easier to play than others. One of the awesome things about guitar is that you can play songs in any key –– from D major to E minor to G♯ harmonic minor (a non-diatonic minor scale with a natural 7th note) to B♭ melodic minor (a non-diatonic minor scale with a natural 6th and 7th).
The C minor scale for guitar, starting on the 6th string. So, in the key of C minor, you would get C D E♭ F G A♭B♭. The same principle applies to the (natural) minor scale, but in a different pattern –– WHWWHWW. So, if the lead singer asks for the key of C (or C major), you would use the 7 notes from the C major scale. Keys take their name from the root note of the scale. The C major scale for guitar, starting on the 5th string If we apply the major scale pattern, we get these notes: C D E F G A B. Major scales are diatonic scales with the following pattern: Whole step, Whole step, Half step, Whole step, Whole step, Whole step, Half step (or WWHWWWH).
On a guitar fretboard, notes that are a whole step apart are two frets away from each other. They highlight 7 notes that create the most consonance (pleasant sounds).Īside from 2 half steps, diatonic scales contain 5 whole steps (also called tones or whole tones). Instead, most guitar keys are based on diatonic scales. Technically, you could write a guitar song based on a chromatic scale. However, it’s more common to stay in the same position on the guitar neck (ex: the 1st-4th frets) and play notes on different strings. For example, in the C chromatic scale, you could start on the 1st fret of the 2nd string and play every note to the 13th fret. What does this all mean for guitar? Well, for every half step, you slide up one fret on the fretboard. This is because they are enharmonic equivalents.They’re the same note, written differently depending on whether there’s another C or D note in the scale. You may be wondering why notes like C♯ and D♭are listed together. As you can see (in standard notation especially), there are no sharps or flats between E and F or B and C (Created using Flat). You can then play the scale an octave higher, starting with the next C. For example, the C chromatic scale is: C, C♯/D♭, D, D♯/E♭, E, F, F♯/G♭, G, G♯/A♭, A, A♯/B♭, B. Chromatic scales contain all 12 notes in a sequence.
Each note is a half step (also called a half tone or semitone) higher than the previous one. In Western music, there are 12 different notes you can play. This way, you’ll know exactly how they work together to form lead and rhythm guitar parts. But it’s still helpful to look at the individual notes that make up keys. If you’re a rhythm guitar player, chances are you’ll be working mainly with chords.
