What 7/8 time means
Seven eighth notes fill the bar, and seven cannot be split into equal twos or threes, so 7/8 is an odd meter (an irregular or asymmetric meter). Every bar contains two two-pulse groups and one three-pulse group, and where the three sits is what gives a particular piece its character. The three most common groupings are 2+2+3 (the three at the end, the default this site and the Metro Gnome app use), 3+2+2 (the three first) and 2+3+2 (the three in the middle).
Think of it as a bar of 4/4 with the last eighth note cut off, or a bar of 6/8 with one extra. Both descriptions are true, and which one a piece leans toward decides whether it feels like a rock groove that keeps tripping or a jig with a hitch.
How to count 7/8
2+2+3: count ONE two ONE two ONE two three, accents on pulses 1, 3 and 5. The bar rolls along in twos and then holds for a beat at the end. This is the grouping the tool above defaults to.
3+2+2: count ONE two three ONE two ONE two, accents on 1, 4 and 6. The long group leads, which is how the Greek kalamatianos is danced.
2+3+2: count ONE two ONE two three ONE two, accents on 1, 3 and 6. Less common, and the hardest to hold at speed because the long group is buried in the middle.
At any real tempo you will not be counting seven; you will be counting the three groups, short-short-long or long-short-short, which is why fixing the accents matters far more than counting the pulses.
What 7/8 feels like
7/8 has a catch in it. In 2+2+3 the bar keeps threatening to settle into a 4/4 groove and then holds one pulse too long, so the listener is pulled forward into the next bar. That forward lean is why it turns up so often in Balkan dance music, in progressive rock and in film cues that need to feel urgent. In 3+2+2 the effect reverses: the bar starts with a stretch and then hurries to close, which is more of a lilt than a lurch.
Songs and pieces in 7/8
- Ruchenitsa (Bulgarian folk dance): the textbook 2+2+3, danced in a fast seven for centuries before prog rock discovered it.
- Kalamatianos (Greek folk dance): the same seven grouped 3+2+2, the long step first.
- Tom Sawyer (instrumental section) (Rush): the synth-led middle section shifts into 7/8, one of rock's best-known excursions into seven.
- 2 + 2 = 5 (Radiohead): the opening section is in 7/8, and the lurch is the whole mood of the song.
- Straight to My Heart (Sting): a pop song that sits in 7/8 for its entire length without ever sounding like an exercise.
How to practise 7/8 with a metronome
Say the groups, not the numbers. Before you play, speak the bar as words with the click running: ap-ple ap-ple pine-ap-ple for 2+2+3. Word rhythms carry the accent naturally and stop you counting a flat one-to-seven.
Find the three. The three-pulse group is the anchor of any 7/8 bar. Locate it in the piece you are learning, put the accent on its first pulse, and make sure the tool is grouping the same way, because a click that accents the wrong pulse trains the wrong bar.
Start under 100 BPM on the eighth note. The tool's BPM is the eighth-note pulse. Around 90 to 100 you can still hear every pulse; above 140 you can only feel the groups, which is where you want to end up, but not where you should start.
For the theory behind why the bottom number never changes a meter's class, and how simple, compound and odd meters relate, see Time Signatures Explained. For any meter not covered here, the odd meter metronome plays anything from 1 to 16 beats with its natural grouping.
