Why 150 BPM Sixteenth Notes Are Fast Enough

Do the math: how fast is your shred really?

Let’s translate the tempo into numbers. With a quarter-note beat, 150 BPM × 4 sixteenth notes = 600 notes/minute = 10 notes/second.

• Sixteenth notes at 150 BPM = 10 notes per second
• Sixteenth notes at 180 BPM = 12 notes per second
• Sixteenth notes at 240 BPM = 16 notes per second

On paper, that looks impressive.
On a metronome, it feels impressive. Use the Smart Click Metronome to practise the subdivision against a steady pulse.

But your ear is not a metronome.
Your ear is a pattern detector with limits.

What the ear actually hears at high speed

At 10–12 notes per second, clear detail can become harder to follow, depending on the playing, tone, recording and listener:

• Individual pick strokes may be less distinct.
• Micro-dynamics or subtle timing choices may be less obvious.
• You may notice texture and energy more than individual notes.

At 16 notes per second – 240 BPM in sixteenths – clarity depends on more than the tempo alone.

With dense distortion and unclear articulation, a run can sound like a buzz.

Instead of distinct musical phrases, you may hear:

a continuous texture
a mosquito-like buzz with heavy distortion
a blurred wall of sound

A fast passage can still have musical meaning. But if its phrasing is unclear, listeners may hear only “fast and loud” and lose interest.

The problem isn’t just taste: sound and perception matter

Taste is only part of the picture.

The reason many people don’t like shred isn’t just “they don’t get it” or “they don’t understand real music”.

It also helps to consider:

• how rapid notes can blend into a continuous texture
• how tone, dynamics and articulation affect clarity at high speed
• how the recording, musical context and listener’s experience affect what stands out

Note density matters, but there is no universal perceptual cutoff at 150 BPM.

It is tempting to think more BPM = more emotion, more impact, more “advanced”.
But a higher number does not guarantee a clearer or more expressive phrase.

Where speed still makes sense

None of this means speed is useless. That is also the point of why shredding is not bad: speed is a tool whose value depends on how you use it.

Speed is powerful when it serves:

• Contrast – a short burst of shred after a slow, lyrical line
• Climax – building tension and releasing it in a controlled run
• Character – a specific, aggressive texture that fits the song

At around 120–150 BPM in sixteenths, you have plenty of speed to work on:

• Making both speed and phrasing audible
• Shaping dynamics and accenting certain notes
• Making deliberate timing choices

Faster passages can work too. The question is whether another 10 BPM improves the musical effect or simply raises your practice record.

Why I tell students: 150 BPM is the line

So why do I draw a line at 150 BPM sixteenth notes?

It is a practical training benchmark, not a law of nature. At that tempo, I want students to demonstrate:

• Reliable coordination.
• Synchronized picking and fretting hands—see these tips for better guitar pick technique for related picking work.
• Muting that is under control.
• Consistent time feel within the phrase.

From there, weigh further speed work against other priorities:

• How much practice time does another 5–10 BPM require?
• Are you keeping the movement controlled rather than adding tension?
• Will the extra speed serve the music you want to play?

If your music calls for 180, 200 or 220 BPM, that can be a useful goal.
Just distinguish a musical requirement from chasing personal records for their own sake.

Injuries and the illusion of progress

There is no injury threshold at 150 BPM. Whatever the tempo, watch how you practise:

• Excessive tension in your wrist and forearm
• Long, repetitive drills without enough rest
• Compensating with bad posture and locked muscles

Feeling that you are “finally getting fast” is not a reason to ignore discomfort or deteriorating control.

They confuse:

• Speed gains with musical growth
• Increasing BPM with increasing value

Pushing harder and treating pain as proof of progress can encourage the wrong mindset:

“I sacrificed my body for my art.”

A number on a metronome is not worth practising through pain.

What you could be working on instead

If you’re somewhere between 120 and 150 BPM with reliable sixteenth notes, you already have a useful amount of speed for many musical situations.

As discussed in guitar technique vs feel, technical ability and musical expression work together. Alongside speed, give practice time to:

• Tone – making every note sound full, intentional and vocal
• Phrasing – shaping lines like sentences, with commas and full stops
• Time feel – learning to sit behind or ahead of the beat on purpose; explore Rhythm Hearo for rhythm practice
• Dynamics – making your lines breathe instead of speaking at one volume
• Note choice – choosing notes that tell a story, not just fill a space

If you want a mindset reset around this, read my article on fast-food guitar vs real music. It will challenge how you think about speed, ego and actual musicianship.

The hard truth about shred

So let’s put it brutally simple.

• At 150 BPM sixteenth notes, you’re already objectively fast.
• Above that, ask whether extra BPM serves the song or only the target.
• Clarity at 12–16 notes per second depends on articulation, tone, phrasing and context, not a universal hard ceiling.

The audience isn’t stupid.
They’re not “too dumb to understand shred”.

If a passage sounds unclear, they may simply be reacting to what they hear:

“This is a blur. I can’t feel anything anymore.”

So here’s the question you have to answer:

Will the next 5 BPM help your music, or would you gain more by using the speed you already have
to play something worth hearing?

FAQ

How fast are sixteenth notes at 150 BPM?

With a quarter-note beat, you play four sixteenth notes per beat. At 150 BPM, that is 600 notes per minute, with 0.1 seconds between evenly spaced note attacks.

How many notes per second is 150 BPM in sixteenth notes?

Continuous sixteenth notes at 150 quarter-note beats per minute equal 10 notes per second: 150 × 4 ÷ 60 = 10.

Is 150 BPM fast on guitar?

Continuous sixteenth notes at 150 BPM are fast playing. The difficulty depends on the phrase, technique, string changes and how long you sustain it. Tempo alone does not establish clean execution or musical quality.

Should guitarists practice faster than 150 BPM?

Yes, if it serves their repertoire or goals. Treat 150 BPM as a practical benchmark, not a universal speed or injury limit, and keep timing, clarity and controlled movement central to practice.
