The Difference Between 3/4 and 3/8 Time Signatures - Music Theory
TLDRThe video explains the difference between two common time signatures - 3/4 and 3/8. The upper number indicates how many beats per bar, while the lower number specifies the note value of each beat. 3/4 has 3 quarter note beats per bar, while 3/8 has 3 eighth note beats, so 3/8 is mathematically different but musically quite similar. 3/8 often encourages a faster tempo with more notes crammed in. Compound times like 6/8 and 9/8 group notes in threes, but 3/8 is simple triple time. Overall the choice of 3/4 vs 3/8 is up to the composer's preference.
Takeaways
- 😀 The upper number in a time signature indicates how many beats per bar, the lower number indicates the note value for each beat.
- 🎵 3/4 time has 3 quarter note beats per bar, while 3/8 has 3 eighth note beats per bar.
- 🤔 Despite mathematical differences, 3/4 and 3/8 can sound similar musically.
- ⏩ 3/8 time often encourages faster tempos with more notes per bar.
- 🐢 3/4 time tends to sound more sedate.
- ❗️ Don't confuse 3/8 with a 'compound' time signature.
- 📝 Compound meters like 6/8, 9/8, 12/8 group notes in 3s to define their beats.
- 🎼 The choice of 3/4 vs 3/8 is up to the composer and musical context.
- 📚 Understanding concepts like time signatures will help in music theory study.
- 🎹 Applying theory principles can aid composers, arrangers and performers.
Q & A
What do the numbers in a time signature tell us?
-The upper number tells us how many beats there are in each bar or measure. The lower number tells us what kind of note value constitutes one beat.
What is the difference between 3/4 and 3/8 time signatures?
-In 3/4, there are 3 quarter note beats per bar. In 3/8, there are 3 eighth note beats per bar. So the beat in 3/8 is faster.
What is simple time versus compound time?
-Simple time has 2, 3 or 4 beats per bar. Compound time has 6, 9 or 12 beats per bar, which are grouped into sets of 3 eighth notes.
Is 3/8 time considered a compound time signature?
-No, 3/8 is a simple time signature because it has a 3 on top. Compound meters have 6, 9 or 12 on top.
Why might a composer choose to write in 3/8 rather than 3/4?
-3/8 often creates a quicker, busier feel to the music. The increased number of beams and flags on the faster note values create more visual activity.
What's the difference between 3/4 and 3/16?
-The beat note value is different - 3/4 has 3 quarter note beats per bar and 3/16 has 3 sixteenth note beats per bar. But both are simple triple meters.
Is there a big musical difference between 3/4 and 3/8?
-Not necessarily. Mathematically they are different but musically they can sound quite similar in many ways. It comes down partly to compositional choice.
Why might a score look less congested in 3/4 compared to 3/8?
-Because 3/8 tends to use more faster note values like eighths and sixteenths. 3/4 is more likely to use slower quarters and halves.
What tips are provided for further study?
-The video recommends checking out the online music theory courses at Music Matters and potentially joining the Music Matters Maestros program for additional learning opportunities.
What benefits does the Maestros program offer?
-Benefits include discounts on courses, monthly composer live streams, a forum to submit your compositions for feedback, a community of like-minded musicians, and the ability to ask questions during live chats.
Outlines
😀 The difference between 3/4 and 3/8 time signatures
Paragraph 1 explains the meaning of the two numbers in time signatures. The top number indicates how many beats there are in each bar. The bottom number indicates the note value of each beat. 3/4 has 3 quarter note beats per bar. 3/8 has 3 eighth note beats per bar. So while they are mathematically different, musically they can sound quite similar.
😕 Misconceptions about 3/8 as a compound time
Paragraph 2 clarifies that 3/8 is not a compound time like 6/8 or 9/8. Compound times have 6, 9 or 12 on top and group notes in 3s. But 3/8 has only 3 beats per bar so it's a simple time. Having just 1 beat per bar would be odd and make dull music.
🎵 Practical musical differences between 3/4 and 3/8
Paragraph 3 explains that 3/4 can allow for a more sedate tempo, with less visual clutter on the score. 3/8 may suit a slightly faster tempo with more eighth and sixteenth notes. So composers choose based on the feel they want. But musically 3/4 and 3/8 are quite similar.
