Where does the word “Interval” come from?
|
|
| The word “Interval” comes from the Latin word “Intervallum” which means “space between two walls”. |
|
| What is a musical Interval? |
|
| A musical Interval is the distance between two pitches. |
|
| What is meant by the phrase, “the distance between to pitches”? |
|
| When we speak of the distances between to pitches, we are simply comparing how much higher or lower one pitch is to another. |
|
| What do intervals look like on the piano keyboard? |
|
| On the piano keyboard, an interval is the distance from one key to some other key. |
|
| What do intervals look like on the staff? |
|
| On, the staff, an interval is the distance from one line or space to some other line or space. |
|
| What is a melodic interval? |
|
| A melodic interval is two pitches heard separately. |
|
| What is a harmonic interval? |
|
| A harmonic interval is two pitches heard simultaneously. |
|
|
|
| A ratio is a comparison of two quantities. |
|
|
|
| Pythagoras was a Greek philosopher and mathematician who lived from 570-495 BC. |
|
|
|
| A monochord is an ancient instrument with one string used as a device to measure the ratios between pitches. |
|
| What did Pythagoras discover? |
|
| Pythagoras discovered that musical pitches have certain mathematical ratios to one another. |
|
| What ratio produces the interval of an octave? |
|
| The ratio of 2:1 produces the interval of an octave. |
|
| What ratio produces the interval of a 5th? |
|
| The ratio 3:2 produces the interval of a 5th. |
|
| What ratio produces the interval of a 4th. |
|
| The ratio 4:3 produces the interval of a 4th. |
|
| What do we call it when pitches sound well together? |
|
| When pitches sound well together we call it consonance. |
|
| What do we call it when pitches do not sound well together? |
|
| When pitches do not sound well together, we call it a dissonance. |
|
| Can consonance and dissonance be measured? |
|
| Consonance and dissonance can be measured by the simplicity of the ratio. The simpler the ratio, the stronger the consonance. |

|
|
| A scale is a series of 8 pitches specifically spaced from one another. |
|
|
|
| A major scale is a series of 8 pitches in the following sequence: whole step, whole step, half step, whole step, whole step, whole step, half step. |
|
| Who developed the modern scale? |
|
| The modern scale was developed over thousands of years by many different minds. |
|
| What is the starting point and basis for the scale? |
|
| The starting point and basis for the scale is the octave (8th). |
|
| Why is the octave the starting point and basis for the scale? |
|
| The octave is the starting point and basis for the scale because the octave encompasses all other pitches within it. |
|
| What impact did Pythagoras’ discovery regarding the mathematical relationships between intervals have on the development of the scale? |
|
| Pythagoras’ discovery regarding the mathematical relationships between intervals resulted in the theoretical basis for the whole tone. |
|
|
|
| A whole tone is the difference between an interval of a 5th and an interval of a 4th. |
|
|
|
| A tetrachord is a series four pitches within the space of a fourth, most commonly consisting of two whole tones and one semi-tone. |
|
|
|
| A semi-tone is the difference between a fourth and two whole tones |
|
| Why is the discovery of the whole and semi-tone important? |
|
| The discovery of the whole tone and the semi-tone is important because they are the basis for how many and which pitches are in the musical scale. |
|
| What do two overlapping tetrachords result in? |
|
| Two overlapping tetrachords result in the seven notes of the Greek scale. |
|
| What are two most common methods of reading music? |
|
| The two most common methods of reading music are reading by number and reading by letter. |
|
| What is the most efficient way of reading must. |
|
| The most efficient way of reading music is reading by order. |
|
| What is reading by order? |
|
| reading by order is the ability to see the mathematical structure and organized patterns inherent in the music. |
|
| Why is reading by order important? |
|
| Reading by order is important because you will understand what you are playing; by making sense of the notes on the page. you will increase the speed at which you will read and learn music |
|
| Where should your eyes be looking on the page? |
|
| Your eyes should always be a few beats ahead of what your hands are playing. |
|
| What is the direction of the musical line? |
|
| The direction of the musical line is the shape the music takes on the page and conforms to how the music sounds. |
|
| Why is recognizing the musical line important? |
|
| Recognizing the musical line is important because it will reduce the time it takes the fingers to find the next key to play and increase your sight reading ability. |
