Quartal and Quintal Chords

Most chords are constructed from major or minor thirds. Quartal chords are chords that are constructed from fourths. Quintal chords are constructed from fifths.

Quintal Chords:

Quartal and Quintal chords have a suspended un-anchored sound to them that differs form regular chords. This quality makes Quartal and Quintal chords very useful in a composer's chord vocabulary.

The French composer Claude Debussy was one of the first composers to use Quartal and Quintal chords regularly. Quartal and Quintal chords are now common in jazz, rock music and TV and film music. Quartal chords are also easy to play on the guitar due to the fact that the standard guitar tuning is mostly fourths.

The Keyboard

The Keyboard is arranged so that the pitch goes left to right, low to high. The keys on keyboard instruments are arranged in a reoccurring pattern. The black keys are arranged in groups of two and three between the white keys.

This pattern continues up and down the keyboard.

The note names of the white keys are:

This key pattern repeats on the keyboard so that the note names of the white keys keep repeating: CDEFGAB-CDEFGAB-CDEFGAB and so on.

Sharps and Flats:

If we take a white key, D for example, and we go up (to the right) to the adjacent black key we are now on the note D-sharp. If we go down (to the left) to the adjacent black key from D we end up on the note D-flat. This is how we determine the names of the black keys and therefore all black keys will be a sharp or flat note.

You may have noticed that black keys can have more than one note name. For example C-sharp and D-flat are on the same black key, but which name we should use depends upon context, such as the Key Signature.

Half-steps and Whole-steps:

A Half-step is the distance of two adjacent notes, such as D to D-sharp, E to F, or A-flat to G. (A half-step is also known as a minor second.)

A Whole-step is the distance of two Half-steps, such as C to D, E to F-sharp, or B-flat to A-flat. (A whole-step is also known as a Major second.)

Alto and Tenor Clefs

(You might want to read about the Staff before you read about the Alto and Tenor Clefs.)

The Alto and Tenor Clefs have two curves that meet in the center. The line on the staff where these curves meet is the note C. These clefs are also called C Clefs for this reason.

The Alto Clef is positioned on the middle line. This line becomes the note C. (This note is also Middle C.)

The note names in Alto Clef are:

Tenor Clef is very similar to Alto Clef but the main difference is that the Tenor Clef is positioned on the second line from the top whereas Alto Clef is positioned on the middle line. In Tenor Clef the second line from the top becomes the note C. (This is also Middle C, just like in Alto Clef.) The note names in Tenor Clef are:

The Staff, Treble Clef and Bass Clef

Music is most commonly notated using the Staff (and tablature.) The staff consists of five horizontal lines on which musical notes lie. The lines and the spaces between the lines represent different pitches. Lower pitches are lower on the staff and higher pitches are higher on the staff.With the blank staff we can't yet tell what notes to play. We use Clefs to tell us which notes correspond to which lines or spaces. The most common clefs are the Treble Clef (also known as the G Clef) and the Bass Clef (or F Clef).

The Treble Clef spirals around the second line from the bottom. This spiral tells us that notes on this line are G.

From here we can figure out the other note names simply by going forward or backward through the musical alphabet: A,B,C,D,E,F,G.

If we need more notes above or below the staff we add Ledger Lines, which extend the range of the staff. (Middle C is the first ledger line below the staff in Treble Clef.)

The Bass Clef has two dots, above and below the second line from the top. The dots tell us that this line is F.

The note names in Bass Clef are:

Middle C is the first ledger line above the staff in Bass Clef.
