Listen like a musician
Put the whole course together into one method: four passes that take any song you hear and give you its tempo, its meter, its key and its chord pattern.
The four passes
- Pass one · the pulse
Tap along until your taps are even, ignoring the singer. Count taps for 15 seconds and multiply by 4 for the tempo in BPM.
- Pass two · the grouping
Find the heavy beat and count ONE two three four with ONE on it. If ONE slides off, count in three. Watch for a pickup before the first strong beat.
- Pass three · home and its colour
Hum the note the song rests on and find it on a keyboard. Then test the note 4 half steps above it and the one 3 above: four means major, three means minor.
- Pass four · the chord pattern
With home as I, listen for the return to home, the chord that leans hardest back to it (V), the relaxed step out (IV) and the darker one (vi).

Sara taps along with a song for 15 seconds and counts 33 taps. She then notices that the weight lands on every third tap. What should she write down?
- About 33 BPM, in 3/4
- About 495 BPM, in 3/4
- About 132 BPM, in 4/4
- About 132 BPM, in 3/4
Show the answer
About 132 BPM, in 3/4
Right. 15 seconds is a quarter of a minute, so 33 × 4 is about 132 BPM, and a heavy beat every third tap means bars of three.
PASSES ONE AND TWO
The clock
Start with the part of a song that needs no theory at all: the pulse. Get your taps even first and measure the speed. Then stop caring about speed and ask where the weight is. Speed and grouping are two different facts and you find them one at a time.
Do both with the singer muted in your head. Drums and bass are honest about the beat; a good singer pulls against it on purpose, which is exactly what makes a vocal sound alive and a beginner lose the count.
Nika hears a song in a cafe. Passes one and two, with nothing
but a watch and her hand on the table.
taps in 15 seconds ......... 25
25 x 4 ..................... about 100 BPM
weight lands on ............ every 4th tap
first sound she hears ...... two quick syllables that arrive
BEFORE the first heavy beatAbout 100 BPM, in 4/4, starting with a pickup.She has not named a single note yet. Already she could count the band in at the right speed, say where the bar lines fall, and work out that an 8-bar intro would last 16 seconds. That is all of lessons 1 to 3, used in about a minute.
Check yourself
- Song A: Omid counts ONE two three four and his ONE lands on the heavy beat every single bar.
- Song B: Omid counts ONE two three four and after two bars his ONE has slid onto a light beat.
His taps are perfectly even in both. What is different about song B?
- Its tempo is faster than song A
- Its beats are grouped in threes, not fours
- It has no strong beat at all
Show the answer
Its beats are grouped in threes, not fours
Right. When ONE will not stay on the heavy beat, the pulse is fine and the grouping is wrong. Three is the next thing to try.
PASS THREE
Home and its colour
Hum along until you find the note the song keeps returning to, the one that makes a line feel finished. Find it on a keyboard by trying notes until one matches your hum: that note is home. Then test its colour. Play the note 4 half steps above home, then the one 3 half steps above. One of them belongs to the song and the other sounds wrong. Four means major, three means minor.
If home is D, and F# fits while F sounds wrong, the song is in D major. If F is the one that fits, it is D minor. The third above home is the single most useful thing you can test at a keyboard.
Pass three, at a keyboard.
the note Nika keeps humming ...... matches D
4 half steps above D ............. F# fits the song
3 half steps above D ............. F sounds wrong
so: home = D, colour = major
D major, built with W W H W W W H from D:
D E F# G A B C# D
W W H W W W H
key signature: two sharps, F# and C#The song is in D major.Two sharps is the second step clockwise on the circle of fifths: C, G, D. If the song had come to rest on B instead, using these same seven notes, it would be B minor, D major's relative.
Check yourself
A song keeps coming to rest on D, and the note four half steps above D clearly belongs to it while the note three half steps above sounds wrong. The song is in D major.
Show the answer
True
True. The third above home is what separates the two scales: 4 half steps is a major third and gives D major, 3 half steps would give D minor. Everything else about the key follows from that one test.
| What Nika worked out | Her answer | From lesson |
|---|---|---|
| Tempo | about 100 BPM | 1 |
| Meter | 4/4, with a pickup | 2 |
| Key | D major, two sharps | 5, 10 |
| Chord loop | D, A, Bm, G, which is I–V–vi–IV | 8, 9 |
| Why the tune sits well | the held notes are chord tones | 11 |

Nika's song is in D major (D E F# G A B C#). Which chord is doing which job?
- D (D F# A)
- A (A C# E)
- Bm (B D F#)
- The chord the last note of the song sits on
- The chord containing C#, the leading tone
- The chord whose root is three half steps below D
Show the answer
I · home: D (D F# A), The chord the last note of the song sits on
V · tension: A (A C# E), The chord containing C#, the leading tone
vi · the minor relative: Bm (B D F#), The chord whose root is three half steps below D
When the song refuses to fit
- Your ONE settles in neither four nor three? Try six quick beats felt as two groups of three: that is 6/8, the shish-o-hasht feel from lesson 2.
- The chorus suddenly sounds brighter and home seems to have moved? The song has changed key. Start the method again from there.
- The chords fit the numerals but the song rests on the sixth note of the scale? You are in the relative minor, not the major.
- Nothing on the keyboard matches the singer at all? The recording may be tuned slightly away from standard, or it may be Iranian classical music, whose intervals a piano cannot play (lesson 4).

Match each thing you notice in a song to the idea that names it
Show the answer
- Your foot taps about 100 times a minute → Tempo, measured in BPM
- Every fourth beat feels heavier → A bar of 4/4
- The tune keeps coming to rest on D → D is the home note
- The chord before the last one leans hard towards home → V resolving to I
- A quick note between two notes of the chord → A passing note
Course recap
- Pass one and two give you the clock: tempo in BPM, then the grouping into bars, watching for a pickup.
- Pass three gives you the key: hum home, find it on a keyboard, then test 4 half steps above it against 3.
- Pass four gives you the chords: I where it rests, V leaning back, IV a step out, vi for the darker moment.
- A melody sits well over its chords because its long notes are chord tones; the quick ones in between are passing notes.
- You will get it wrong sometimes. Every wrong guess narrows the next one, which is how every musician learned this.
