The Basics of Musical Harmony

Musical Harmony

Many different elements comprise music. The basic rhythm and time signature make up one part, while the melody and chord structure make up another. Harmony is just one more of the important elements of musical compositions. But what is it and how is it used?

Musical harmony can be described in several ways. For a basic definition, harmony is simply two or more pitches played simultaneously. This is how basic chords are built. By combining multiple pitches, usually at least three, a chord is formed. There are a thousand different types of chord, even though many of these don’t appear in Western music.

Harmony is also defined as the counterpart to melody. For example, by adding a melodic line a major or minor third above the melody, a harmony is created. Whether the third is major or minor depends entirely on the scale used in the melody and chord progression. Using the wrong kind of third results in a musical clash, or dissonance.

Different kinds of harmonic structure result from using different intervals. The fifth is a commonly used harmonic device. This results from adding a note a fifth above the melody and is very universal. Most scales tones can be separated by a fifth, so there aren’t as many odd notes using this type of harmonic theory.

More complex harmonic structures require a greater knowledge of musical theory. Using the seventh is common to give the melody more of a blues or jazz feel. Jazz harmonies can often be quite complex, spanning the octaves to add ninths, 11ths or 13ths. These intervals can be hard to keep in tune when performed by vocalists, as the span between notes is great. Great vocal groups often use harmony to create chords with their voices.

One argument about harmony versus dissonance lies in the perspective of the listener. An extremely dissonant group of notes may sound absolutely beautiful to one set of ears, while sounding completely terrible to another. A lot of non-Western and avant-garde music uses the concept of dissonance to great effect. For example, a melody that begins with the C note may have C# an octave above it added. To certain listeners, this sounds absolutely frightful, while others sing its praises. Harmony is in the eye of the beholder.

Different harmonic ideas can be presented by using inversions. Inversions involve taking the lowest tone of a chord and transposing it up an octave. For example, a C major chord consists of the notes C, E and G. Taking the lowest tone, the C, and moving it up an octave creates the same chord with the notes E, G and C. This gives a different harmonic feel to the chord, allowing different notes to stick out more than others. This technique is very useful when devising harmonic movements.

Musical harmony is a simple concept, yet it contains so many variations that it is inexhaustible. With these simple rules, anyone can learn the basics of harmonization and be on their way to composing the next great song.

10 Piano Styles You Can Learn To Play

Piano Styles You Can Learn To Play

When studying the piano, a student encounters a myriad piano styles. To master the instrument, at least several of these styles must be learned, and all if at all possible. Knowledge of various playing styles enables a pianist to enjoy and play in any genre and to cross-polinate styles to create a fusion he or she can call their own.

Many modern piano styles are based on the blues. The blues involve an emphasis on the major and minor pentatonic scales, with an additional note included. The flatted fifth is added to the minor pentatonic to create the blues scale. Many blues songs are based on a simple chord progression, known as 12-bar blues. This uses the I, IV and V chords of a scale to create a foundation for melodies and solos.

For example, rock piano was born out of the blues and then took on a life of it’s own in the stylings of Jerry Lee Lewis, Michael McDonald, Elton John, Billy Joel, and many others.

Cocktail piano is a style generally connected with Liberace, Eddy Duchin, Roger Williams, and others who play popular tunes with lots of great technique — lots of notes, runs, flourishes, and so on. But I hate to catagorize and of these great pianists, as many of them play in other styles as well.

Boogie-woogie is a piano style based on the blues. It started as a solo piano style, but has expanded into other genres, such as county-western and gospel. It differs from the blues in that it is considered dance music, while blues music traditionally expresses sadness and frustration.

Rhythm and blues piano is based on blues, jazz, and gospel styles. As the name suggests, the emphasis is on the rhythm of the song. Most R&B has a particular swing to it, with a strong feel of syncopation in the rhythm. Syncopation involves placing the stress on a normally unstressed beat. This often results in an almost off-time feel to the untrained ear.

Ragtime piano also incorporates syncopation. Ragtime uses syncopation in its melodies by placing melodic notes between the stressed beats of the rhythm. Ragtime is often considered the first completely American genre, even predating jazz.

Jazz piano encompasses such a broad palate of styles that it is impossible to describe. Many piano styles incorporate ideas borrowed from jazz, such as improvisation. An emphasis on extended chord forms also stems from jazz piano.

New age piano often involves less chord changes than other styles, instead relying on simple two-chord progressions and polychords. A polychord occurs when two different chords are played at once. This technique is taken from earlier classical works by composers such as Stravinsky.

Gospel piano is often similar to the blues, jazz and R&B. It emphasizes certain extended chords, such as the 11th, and usually has the swinging feel associated with jazz and R&B. The apparent simplicity of gospel songs often hides the fact that they are, indeed, quite musically complex. Syncopation is highly stressed in gospel music, as it contributes to the overall spiritual feel of the music.

Country and western piano has similar roots as blues piano. Both styles stem from earlier folk styles, often developed by the less fortunate people of the era. Many early country songs stem from Appalachian folk songs. Country and western piano is highlighted by very bright playing, with simple chord progressions underneath the melody.

Traditional sacred piano styles involve the playing of liturgical songs and hymns. These can range from the harmonically and rhythmically complex to simple two and three chord songs. Many hymns stem from folk songs of centuries past. The variety of sacred piano styles is as numerous as the liturgical songs themselves. These piano styles often involve a strict reading of notation, with less of an emphasis on personal interpretation than other styles.

The classical piano style is probably the most varied of all the styles. Classical music is older than other styles, and is considered to the proper grounds for musical instruction. Many elements of other piano styles come from classical music, and nearly all forms of musical theory are used in classical music. Classical music usually requires intense training to master, though there many pieces designed with the novice player in mind.

Though classical is often considered the high point of music, this “ain’t necessarily so.” For instance, many players who are “classically trained” have trouble adapting to the feel and sincerity of the blues. For this reason, a well-rounded player should be adaptable and learn as much about each of these piano styles as possible. In this way, a pianist is ready for any musical challenge. And besides, who knows where the future of music lies?

Tritone Chord Progression

Tritone chord progression

Just what is it about the tritone chord progression that makes it so mysterious? Perhaps it has to do with its dissonant, clashing sound. It may have something to do with its dubious history. Whatever it is, the tritone chord progression in music made a comeback in music after several centuries of bad publicity.

‘Tritone” is defined as a musical interval that spans three whole tones. A tritone chord may also be called an augmented fourth or diminished fifth chord. The tritone sounds like a clash, or as a dissonant chord. For this reason, the tritone chord was often avoided during Medieval times through to the end of the Romantic era.

For hundreds of years musical styles were, in large part, dictated by the church. During Medieval times, the tritone was viewed as too dissonant for use in common liturgical services. In fact, the tritone chord progression came to represent the devil. Perhaps as early as the 18th century it was commonly known as “diabolus in musica” (the devil in music). A great deal of superstition came to be associated with the tritone. Some church fathers in the Catholic church adhered to the belief that it may even serve to invoke the power of the devil. Because of this belief, the use of the tritone was banned by the church for liturgical use. Because of this negative association, even secular music produced during these centuries avoided it.

There is speculation that this chord may have been associated with the Devil for another reason. The tritone, as already mentioned, consists of three whole tones. Three whole tones equal six semitones. This may have led Christians to associate the tritone with the Biblical “mark of the beast,” or number of the devil: 666.

As with any widely held superstition, the tritone had a bad public image to overcome. Eventually some musicians cautiously experimented with the tritone, particularly during the Baroque and Classical music era. Finally, it seemed as though its stigma had been somewhat overcome during the Romantic period. Notable classical musicians like Vivaldi, Beethoven and Debussy inserted the tritone into various works.

When the equal temperament system of tuning came into general practice in Western music, the tritone began to make a comeback in contemporary songs. Still, it had remnants of its former reputation. The tritone began to appear in modern rock and roll, jazz and blues songs. Those with prudish natures denounced it, probably still subscribing to the old-fashioned church-propagated superstition. Despite some opposition, the tritone took hold. Today it’s used regularly and without inhibition.

Many musicians are still aware of its diabolical history. In fact, the tritone is sometimes still used in contemporary media to signify, represent or “invoke” the devil. One example of this is the 1986 movie Crossroads. In it, the main character, in a showdown of guitar prowess, ends a guitar solo with a tritone chord because of its association with the devil. However, its relation to ancient superstitions has been largely forgotten by the general public. Today, the tritone is used artistically, just another color in the musical palette.
