TLDRThe video explains how to properly beam notes in compound time signatures like 6/8. It first reviews key concepts - simple vs compound time, time signature numerators indicating beats per measure, denominators indicating note units per beat. In compound time, beats divide into groups of 3, not 2 as in simple time. So in 6/8, the 6 quavers per measure are beamed in groups of 3, representing 2 dotted crotchet beats. After analyzing a musical example, the principles are applied to correctly beam the notes - group them into beats, use dots instead of ties when possible inside beats, reflect the rhythmic flow. Proper beaming helps performers interpret and keep rhythm.

Takeaways
  • 😀 Understanding time signatures like 6/8 is key to properly beaming notes
  • 🎶 In compound time signatures, divide into groups of 3 notes per beat
  • 🎵 Beam notes that belong to the same beat together
  • 🎼 Use dots instead of ties when possible inside a beat
  • 🎹 Seeing proper beaming helps identify beat divisions
  • 🎼 Simple time divides beats into 2s, compound into 3s
  • 👍 Beaming reflects the rhythm and beat structure
  • 🎻 Fix beaming to make rhythm easier to see and play
  • 🎼 Count 6/8 as 2 beats with 3 subdivisions each
  • 🎶 Composing and arranging need proper beaming
Q & A

  • What is the main issue being discussed in the video?

    -The main issue is how to properly beam notes together in 6/8 time, which is a type of compound time signature.

  • What do the numbers in a time signature tell you?

    -The top number tells you how many beats are in each bar or measure. The bottom number tells you what type of note gets one beat. So in 6/8 time, there are 6 quaver beats in each bar.

  • What is the difference between simple time and compound time?

    -In simple time signatures like 2/4, 3/4, and 4/4, the beats divide naturally into two equal parts. In compound times like 6/8, 9/8, and 12/8, the beats divide naturally into three equal parts.

  • Why do you need to beam notes in groups of three in 6/8 time?

    -Because 6/8 is a compound time, you need to divide it into two groups of three quavers. Each group of three quavers makes up one dotted crotchet beat. So beaming reflects these beat groupings.

  • When should you use a dot instead of a tie when beaming?

    -Use a dot instead of a tie whenever possible if the notes are inside the same beat. For example, two tied quavers could be replaced by one dotted quaver inside a beat.

  • Why is proper beaming important?

    -Proper beaming makes the music easier to read and interpret. It shows the beat groupings clearly so performers can keep track of the rhythm.

  • What do exam questions often require students to do with beaming?

    -Exams often give students an extract of music and ask them to beam the notes correctly to show the beat groupings.

  • Why do some people struggle with beaming notes properly?

    -Some people don't fully understand time signatures, especially compound times. Also, music notation software sometimes beams things oddly.

  • What is the step-by-step process for beaming notes in 6/8 time?

    -1) Divide into groups of 3 quavers. 2) Beam each group of 3 quavers together. 3) Interpret each group of 3 as 1 dotted crotchet beat. 4) Make sure beaming reflects the 2 main beats per bar.

  • How can you check if you have beamed notes correctly?

    -If the beaming clearly shows 2 strong beats per bar, with 3 quavers grouped together inside each beat, then it is likely correctly beamed for 6/8 time.

🎵 Understanding Compound Time Signatures and Note Beaming

Paragraph 1 explains that the example music extract looks sensible but is incorrectly beamed, which would trouble someone doing music theory exams or composing/arranging music. It establishes that the time signature is 6/8 compound time, with 6 quavers per bar grouped in twos.

🎶 Organizing Notes into Beats in Compound Time

Paragraph 2 demonstrates how to organize the notes into two beats per bar by grouping the 6 quavers into twos. It shows how the beaming should reflect the beat grouping. It also recommends using dots over ties where possible.

🎼 Completing the Correct Beaming

Paragraph 3 walks through beaming the remaining bars correctly by identifying which notes belong to each beat in the bar. It emphasizes how correct beaming makes the music easier to read and perform.

Keywords
💡beaming
Beaming refers to the way notes are grouped together on the musical staff using beams or flags. Proper beaming is important for indicating the meter and rhythmic organization of music. In the video, the instructor discusses how notes should be beamed together in 6/8 time to properly indicate the compound meter with two beats per bar.
💡compound time
Compound time is a type of meter in music with 6, 9, or 12 as the top number in the time signature. It indicates that each beat divides into three subdivisions, creating a feeling of lilting subdivision in the music. The instructor explains that 6/8 time is an example of compound time.
💡dotted notes
Dotted notes are notes with dots after them, which elongate the note duration by half. The instructor recommends using dotted notes instead of ties whenever possible inside a beat to improve clarity of the meter and beats.
💡grouping
Grouping refers to organizing notes into logical units that align with the meter and beats of the music. The instructor demonstrates how to group notes in 6/8 time into groups of three eighth notes to delineate the two main beats per bar.
💡meter
Meter refers to the rhythmic framework of beats in music denoted by the time signature. Simple and compound meters group beats differently. The instructor analyzes the 6/8 time signature to determine the appropriate metric grouping and beaming.
💡rhythm
Rhythm refers to the pattern of long and short durations in music. Beaming together notes of values that belong in a beat unit helps indicate the rhythmic organization. The instructor shows how proper beaming clarifies the rhythm.
💡simple time
Simple time consists of time signatures with 2, 3, or 4 as the top number, indicating division of beats into two equal parts. This contrasts with compound time, which divides beats into three equal parts.
💡subdivision
Subdivision refers to dividing beats into smaller rhythmic units. In compound time like 6/8, each beat divides into three subdivisions instead of two like in simple time.
💡ties
Ties connect two notes of the same pitch across bar lines or beats. The instructor recommends using dotted notes instead of ties to connect notes within a beat to improve metrical clarity.
💡time signature
The time signature indicates the meter of music with two numbers - the top number specifies how many beats are in each bar, and the bottom number indicates the note value for a beat. 6/8 is a compound time signature with 6 eighth note beats per bar.
