Music Expression – The Marks on Musical Sheets

Music expression is the surface details of musical sound. Thus, it is how the music is played or expressed.

Why do people listen to music? It is because music’s expression grabs our attention and evokes our emotional response.

In order to read, write, or understand music, one must learn the expression signs, words, and abbreviations, in other words, the musical vocabulary.

Basic Terms

Let’s first define some of the commonly used terms in the music world.

melodyA melody is a succession of single tones.
chordA chord is a combination of tones sounded together.
triadA triad is a three-note chord.
phraseA phrase is a short musical sentence or thought.
The phrase usually ends on a longer note, or at the end of a rhythmic pattern.
periodA period is normally made up of two phrases.
It is often built of similar or parallel melodic tones.

The following are a few examples that relate to these terms.

Expression Marks

The expression marks on the music scores serve multiple purposes:

  • How the tones are related to each other: for instance, the slur and tie marks.
  • When sections of a music piece are to be repeated.
  • Dynamics of tones

Slur and Tie

In music scores, you see curved lines drawn above or below groups of two or more notes. The curved line is the slur. Usually, this means you play or sing the notes smoothly together (we use the Italian word legato).

Sometimes, people may think the slur and legato are the same. They are actually different. The slur is a marking (the curved line), while the legato is a technique to perform the tones.

A tie is a curved line connecting two notes of the same letter name and pitch. You will only play the first note and hold for the second note.

Marks for Repeating

There are various signs to indicate whether to repeat a section or multiple sections.

1st and 2nd endings

When repeating the second time, it goes to the 2nd ending, then either continues to another section or ends the piece.

coda sign

From the “to Coda” sign, jump to the coda section and to the end.

In the article What are the Tone Characteristics? We introduced the tone dynamics and related expression chart, which is the same as the chart below.

Changes in dynamics can be progressive and extend over a period of time. That is where the crescendo and decrescendo come into play.

  • A crescendo is a continuous increase in the volume of sound.
  • A decrescendo is a gradual decrease in the volume of tones. A decrescendo music symbol is also known as diminuendo.

The following shows the crescendo symbol and the descrescendo sign.

An impressive crescendo can generate some spectacular moments in a music piece, while the diminuendo may reach some soothing effects.

To Wrap Up…

It is the expression in music that makes it attractive and catches our attention. The composers use musical expression marks to convey the intention. Many times, it is up to the performers to interpret the music language on the sheet and create expressive music that evokes listeners’ emotions.

As part of learning music or playing the piano, it is essential to learn the music expression symbols. Moreover, for music creators, writing the music with intended expression marks will make the piece ever closer to the original desire.

It seems to have a lot of expression symbols. No worries because you’ll not likely have to remember them overnight. When you progress through your learning, these symbols will appear gradually in your lessons. You will get familiar with them and improve your grasp of them with practice.
