Скачать или смотреть Grade 1 Music Theory: Rhythmic Notation and Note Values

Question 1: A semibreve is written as an open oval, whereas a minim adds a stem to that oval. Adding the stem halves the value of the note, changing it from four beats to two beats.
Question 2: If a stem goes down, it must be attached to the left-hand side of the note head. If the stem goes up, it must be attached to the right-hand side.
Question 3: A dot placed after a note increases its value by half of its original duration. For example, a minim worth two beats becomes three beats when dotted because half of two is one.
Question 4: A staccato marking is a dot placed above or below the note, indicating the note should be played detached. A dotted note has the dot placed after the note head, which changes the length of the note's duration.
Question 5: A stave is the set of five horizontal lines upon which music is written. Various symbols, such as rests, are positioned on specific lines of the stave to indicate their meaning.
Question 6: Both appear as small boxes, but the semibreve rest is "suspended" from the fourth line of the stave. The minim rest is "mounted" and sits on top of the third line.
Question 7: The semibreve rest is also used to indicate that a whole bar is empty. This applies even if the bar is supposed to contain only two or three beats rather than four.
Question 8: Each hook added to a note halves its value. A quaver has one hook and is worth half a beat, while a semiquaver has two hooks and is worth a quarter of a beat.
Question 9: A dotted minim is worth three beats. This is calculated by taking the original two beats of the minim and adding one beat, which is half of the original value.
Question 10: While usually written as a specific jagged symbol, a crotchet rest can sometimes appear as a "backward seven" in older music. This distinguishes it from a quaver rest, which looks like a standard seven.
Crotchet: A note value worth one beat; known in the US system as a quarter note.
Dot: A marking placed after a note that increases its duration by half.
Minim: A note value worth two beats; known in the US system as a half note.
Quaver: A note value worth half a beat, characterized by a single hook on its stem.
Rest: A musical symbol used to notate a specific duration of silence.
Semibreve: A note value worth four beats; known in the US system as a whole note.
Semiquaver: A note value worth a quarter of a beat, characterized by two hooks on its stem.
Staccato: A dot placed above or below a note indicating that it should be played in a detached, short manner.
Stave: The five horizontal lines upon which musical notes and rests are written.
Stem: The vertical line attached to a note head.
Analyze the hierarchy of note values from the semibreve down to the semiquaver, explaining the visual and mathematical relationships between them.
Discuss the dual role of the dot in musical notation, comparing its impact on performance style versus its impact on rhythmic duration.
Explain the significance of silence in music and detail how the various rest symbols allow a composer to precisely notate different lengths of pause.
Compare and contrast the UK and US naming conventions for notes, and explain how the US system provides a mathematical clue to the note's value within a "whole."
Evaluate the importance of the semibreve rest in orchestral or choral scores, specifically regarding its use in representing empty bars across different time signatures.
