Rhythm, Beats, and Time Signatures

What You’ll Learn

Rhythm is the pattern of long and short sounds in music. It is what makes you tap your foot or nod your head. This handout teaches you how rhythm works, what beats are, how note values divide time, and what a time signature tells you — all demonstrated on your guitar so you can feel it, not just read about it.

The Concept Explained

What Is a Beat?

A beat is a steady pulse in music, like a heartbeat or the ticking of a clock. When you clap along to a song, you are clapping on the beats. Beats are evenly spaced — the time between each beat is the same.

Try this: tap your foot at a comfortable, steady pace. Each tap is one beat. That steady tapping is called the pulse or tempo of the music.

Tempo — How Fast the Beats Go

Tempo is the speed of the beats, measured in BPM (beats per minute). A tempo of 60 BPM means one beat every second. A tempo of 120 BPM means two beats per second — twice as fast.

In this course, you will use a metronome (a device or app that clicks at a set tempo) starting from Session 3. Set it to 60 BPM to start — one click per second.

Note Values — How Long Each Note Lasts

Notes have different durations. In 4/4 time (the most common time signature — explained below), here are the basic note values:

Note Value	Duration	How Many Per Bar
Whole note	4 beats	1
Half note	2 beats	2
Quarter note	1 beat	4
Eighth note	1/2 beat	8
Sixteenth note	1/4 beat	16

Think of it like cutting a pie. A whole note fills the entire bar. Cut it in half: two half notes. Cut each half in half: four quarter notes. Keep cutting: eight eighth notes, sixteen sixteenth notes.

Bars (Measures)

Music is divided into equal groups of beats called bars (also called measures). In TAB and standard notation, bars are separated by vertical lines:

e |—0—1—3—0—|—1—3—0—1—|
B |——————————|——————————|
G |——————————|——————————|
D |——————————|——————————|
A |——————————|——————————|
E |——————————|——————————|

The vertical line | marks the end of one bar and the start of the next.

Time Signatures

A time signature is two numbers stacked at the beginning of a piece. It tells you two things:

• Top number: How many beats are in each bar
• Bottom number: What note value gets one beat

4/4 Time (also called “common time”)

• 4 beats per bar
• Quarter note = 1 beat
• Count: “1 - 2 - 3 - 4, 1 - 2 - 3 - 4”
• Used in: most rock, pop, blues, and Hindi film music
• Most songs in this course use 4/4 time

3/4 Time (also called “waltz time”)

• 3 beats per bar
• Quarter note = 1 beat
• Count: “1 - 2 - 3, 1 - 2 - 3”
• Used in: waltzes, some folk songs
• First encountered in Session 7 with “Scarborough Fair”

Counting Eighth Notes

When you need to count eighth notes (which are twice as fast as quarter notes), add “and” between the beats:

“1 - and - 2 - and - 3 - and - 4 - and”

Each number and each “and” is one eighth note. This becomes important when you start using upstroke strumming patterns (first introduced in Session 5).

Rests — Silence Has Rhythm Too

A rest is a measured silence. Just as notes have durations, rests tell you how long to stay quiet:

Rest	Duration
Whole rest	4 beats of silence
Half rest	2 beats of silence
Quarter rest	1 beat of silence
Eighth rest	1/2 beat of silence

Rests are just as important as notes. A well-placed silence makes music breathe.

On Your Guitar

Exercise 1: Feeling the Beat with Open Strings

Set a metronome to 60 BPM (or tap your foot steadily, one tap per second).

Strum the open strings of your Saga SF-600C-BK (all six strings, no fretting hand needed) once per beat — one strum per click:

Strum: DOWN DOWN DOWN DOWN | DOWN DOWN DOWN DOWN |

Count: 1 2 3 4 | 1 2 3 4 |

Each strum is a quarter note. You are playing in 4/4 time. Keep it perfectly even — every strum lands exactly on a click.

Exercise 2: Half Notes and Whole Notes

Same open strum, but now hold each strum longer:

Half notes (strum every 2 beats):

Strum: DOWN - DOWN - | DOWN - DOWN - |

Count: 1 2 3 4 | 1 2 3 4 |

Strum on beats 1 and 3 only. Let the strings ring through beats 2 and 4.

Whole note (strum once per bar):

Strum: DOWN - - - | DOWN - - - |

Count: 1 2 3 4 | 1 2 3 4 |

Strum on beat 1 only. Let it ring for the full bar.

Exercise 3: Eighth Notes — Down and Up

Now double the speed. Strum down on the beat and up on the “and”:

Strum: D U D U D U D U |

Count: 1 & 2 & 3 & 4 & |

D = downstroke, U = upstroke. Your hand moves steadily down-up-down-up. Each strum is an eighth note. This pattern first appears in Session 5.

Keep your wrist relaxed and your strumming motion small. The movement comes from the wrist, not the elbow.

Exercise 4: Counting in 3/4 Time

Strum the Em chord (finger 2 on fret 2 string 5, finger 3 on fret 2 string 4) in 3/4 time:

Strum: DOWN DOWN DOWN | DOWN DOWN DOWN |

Count: 1 2 3 | 1 2 3 |

Notice the different feel — three beats per bar has a swaying, waltz-like quality. Accent beat 1 slightly (strum a little harder) to feel the pulse. This is the feel you will use in Session 7 for “Scarborough Fair.”

Exercise 5: Mixing Note Values

Try this pattern using the Em chord, mixing quarter notes and eighth notes in 4/4:

Strum: D D D U D U |

Count: 1 2 3 & 4 & |

Beat: quarter quarter eighth-eighth-eighth-eighth |

Strum down on beats 1 and 2 (quarter notes), then down-up-down-up on beats 3 and 4 (eighth notes). This combination of note values is extremely common in guitar strumming.

Quick Quiz

1. How many beats are in one bar of 4/4 time?

2. A quarter note lasts how many beats (in 4/4 time)?

3. If a song is at 60 BPM, how many seconds is one beat?

4. What is the difference between 4/4 time and 3/4 time?

5. When counting eighth notes, what do you say between the numbered beats?

Answers

1. Four beats per bar.
2. One beat.
3. One second. (60 beats in 60 seconds = 1 beat per second.)
4. 4/4 has four beats per bar; 3/4 has three beats per bar. 4/4 feels like marching; 3/4 feels like a waltz.
5. “And” (written as ”&”). You count: “1 and 2 and 3 and 4 and.”

Key Takeaway

Rhythm is the backbone of everything you play. A beat is a steady pulse, note values tell you how long each sound lasts, and the time signature tells you how beats are grouped into bars. When you can count “1-2-3-4” (or “1-2-3”) and strum exactly on those beats, you have the foundation for every strumming pattern in this course.
