What is an Interval in Music?

In music, an interval is the distance in pitch between two notes. Intervals are fundamental in building scales and chords. They can be measured in terms of steps and semitones. The most common intervals are:

• Whole Steps: This is the interval between two notes separated by a single note, like from C to D.
• Half Steps: This is the smallest interval in Western music, such as from E to F.

Understanding Interval Quality

Interval qualities provide additional information about the specific sound of the interval. The most commonly used qualities are:

• Perfect: Intervals like unison, fourth, fifth, and octave are classified as perfect because of their consonant sound.
• Major and Minor: These terms apply to seconds, thirds, sixths, and sevenths. A minor interval is a semitone smaller than its major counterpart.
• Augmented and Diminished: Augmented intervals are one semitone larger than major or perfect intervals, while diminished intervals are one semitone smaller than minor or perfect intervals.

Hearing Intervals - Basics

The concept of hearing intervals forms a critical foundation in music theory. By learning to recognize intervals, you can improve your skills in areas such as harmonizing, composing, and sight-reading.

What is an Interval in Music?

An interval is defined as the space between two pitches. In Western music, intervals play a vital role in the structure of melodies and harmonies. By understanding the difference between whole steps and half steps, you can navigate through various musical scales.Here are some basic intervals:

• Whole Step: As seen between C and D, where there's a gap of one note in between.
• Half Step: Seen in the jump from E to F, which is the smallest interval in the chromatic scale.

Understanding Interval Quality

The quality of an interval refers to whether it is major, minor, perfect, augmented, or diminished. Understanding these qualities helps classify the interval further:

• Perfect: Applicable to fourths, fifths, and octaves due to their consonant nature.
• Major and Minor: Referring to intervals like thirds and sixths; a minor interval is a semitone less than its major counterpart.
• Augmented and Diminished: Augmented intervals are larger by a semitone compared to perfect or major, and diminished intervals are smaller by a semitone than perfect or minor.

Techniques for Hearing Intervals

Learning to hear intervals accurately is crucial for developing a keen musical ear. Various techniques can be practiced to enhance your ability to distinguish and identify intervals effectively. Being able to do this helps in a number of musical activities, such as sight-reading, playing by ear, and composing.

Recognizing Intervals by Ear

One effective technique for learning to recognize intervals by ear is through intervallic ear training. This involves:

• Listening to two notes and identifying the interval between them.
• Using a piano, guitar, or another instrument to play intervals frequently.
• Transforming the exercise into a guessing game, where another person plays the notes.

Using Mnemonics and Songs

Mnemonics can be a helpful tool in interval recognition. Associating intervals with well-known songs aids in memorization and recall. For instance:

• The interval of a minor third can be associated with the beginning of the song 'Greensleeves'.
• The start of the 'Star Wars' theme song uses a perfect fifth interval.

Singing and Visualizing Intervals

Singing is another effective technique for solidifying your understanding of intervals. Here's how you can incorporate this into your practice:

• Sing scales while placing emphasis on interval jumps.
• After playing an interval on an instrument, attempt to replicate it vocally.
• Visualize the movement between notes as you sing to strengthen the mental connection.

Exercises for Hearing Musical Intervals

Enhancing your ability to hear musical intervals is an important part of your music education. Engaging in targeted exercises can significantly improve your ear for music. Through practice, you'll develop acute listening skills, enabling you to identify intervals with ease.

How to Hear Harmonic Intervals

Harmonic intervals are pairs of notes played simultaneously. They differ from melodic intervals, where notes are played successively. To hear harmonic intervals, try the following exercises:

• **Interval Identification:** Play two notes together and attempt to identify the interval by ear. Use a piano or a digital tuner for varying pitches.
• **Chord Analysis:** Play simple chords, like a major or minor triad, and focus on the individual intervals within the chord.
• **Singing Harmonics:** Sing the two notes of a harmonic interval simultaneously, or hum them if it helps to better visualize the sound.

Theory of Hearing Intervals

To understand how we perceive musical intervals, it's beneficial to delve into the theory behind interval recognition. This involves:

• Psychoacoustics: The study of how your brain interprets sound waves and associates them with musical concepts.
• Tonality and Context: Intervals may sound different based on the musical context or key signature in which they are placed.
• Frequency Ratios: Identifying intervals with frequency ratios helps to standardize their understanding, such as a 3:2 ratio representing a perfect fifth.
