10,000 Hours of Taiko
A great test of taiko science is now under way!
The book Outliers (review here) proposes the “10,000 hour rule” — mastering anything requires 10,000 hours of practice. As an experiment, I’ve decided to try and track my taiko practice time. I’ve conservatively estimated how many hours completed thus far, and am now carefully recording my daily practice. Watch this site to see when I cross the 10,000 hour mark (probably somewhere between Apr 8, 2017 and Aug 14, 2026) and then we’ll decide if I’ve reached “master” status. :)

Graph generated:
The previous graph shows my progress thus far toward the 10,000 hour mark. Humbling, no? The past four months of diligent time tracking are that tiny, red squiggle on the left. The straight lines represent possible progress estimates. Since I started playing taiko, I’m averaging .9 hours of practice per day. If I continue at that rate, I reach the 10,000 hour goal on Aug 14, 2026, represented by the dark blue line in the graph. Since I started taking detailed notes of my practice time in June of 2009, however, I’ve been averaging 2 hours of practice per day. At that rate, I reach my goal on Apr 8, 2017, as shown by the light blue line. Actual completion will likely be somewhere in-between.
The next graph shows daily hours by practice type: personal practice, practice with On Ensemble, practice with other groups and individuals, and live performance. See below for more on how these numbers are tallied.

Graph generated:
Personal practice time since June 22, 2009: 406.09
Practice time with On Ensemble since June 22, 2009: 173.9
Practice time with other groups/individuals since June 22, 2009: 188.81
Live performance time since June 22, 2009: 59.15
Caveats
Measuring one’s practice time is not without its dangers. Focusing on numbers can encourage uninterested practice and wasted time. I strongly believe that concentration, focus, and enjoyment are essential to quality practice. In the interests of science, however, and because I feel I am suitably aware of the dangers, I am dutifully keeping track of every minute practiced every day. You can read more about my thoughts on practice here.
What counts as practice?
This is a very difficult question. In fact, the ambiguity of defining “practice” is the biggest weakness of the 10,000 hour rule. For the purposes of this experiment, I am measuring only time spent when my brain is focused on taiko technique. By taiko technique, I mean the physical and hand/brain coordination aspects of playing all varieties of Japanese drums. So time spent doing small-drum drills on a practice pad, or playing slant drum in front of a mirror, counts. Working on my timing on my lap while on the bus counts too. Performance counts, but only when it is challenging in terms of playing, timing, or listening technique. In most cases, I’ll give myself about 30 minutes of practice time for every hour of performance. Group practice is tabulated similarly – it only counts when I’m concentrating, which is approximately half the time. Composition, writing about taiko, and teaching taiko do not count. While I believe these elements *do* contribute to becoming a master player — in fact they are probably critical elements — I am trying to err on the side of measuring conservatively.

Wow, this is great! Are the graphs created in wordpress? I’ve seen Tally Graph but these don’t look like google charts…
Hello! I tried using Tally Graph but I didn’t like that I’d be relying on Google’s API for years to come. So my friend Matt Gallizzi and I used gnuplot and cron to create the graphs nightly, and used short-codes in WordPress to actually use the graphs and number tallies on the site. I’ll have a howto coming soon!
I’m looking forward to the tech tutorial… Great job!
This is pretty darn cool Kris! Man, you are making me feel really lazy though! :D Good luck with your goals, I look forward to hearing about the progress!
Kris, your honesty & dedication are humbling. Makes sense that % engagement (or “directed” practice) has to be part of the tally, otherwise we’d all hit 10,000 eventually just phoning it in. :) “How to max out everyone’s engagement % during group practice – including your own” would be a great topic for another tutorial or blog post! One question: what is Err practice?
Wow this is awesome. Go red squiggle go! This makes me want to do a better job at tracking my practice time as well. Seeing the red squiggle gradually inch it’s way up would be a fun way to motivate myself.
Thanks for the encouragement everyone! Margaret, “Err” is the famously difficult solo piece I’m working on. By the time I can play it (I’m hoping in another 12 months or so), it’s very likely I’ll realize the song isn’t actually worth the difficulty level. I’m ignoring that possibility for now though. If nothing else, it helps the 10,000 hours goal. :)
Hah, how funny. When I read that part about 10,000 hours in Outliers, I was actually thinking about you and Shoji.
Egad, Kris! Actually I tried doing the Outliers math before…. I’m 53, so at an hour a day, I could get there near age 80! Seriously, though — thanks for the nudge!
This is way too cool. Like you said, I’m a little afraid of being motivated so much by numbers that I’d start bumping up my practice time just to make the goal faster (instead of constructively improving technique), but I’m gonna be cautious and track my practice time, too. I wanna be cheered on by my personal practice squiggle!
Hey, wouldn’t the red squiggle look more impressive if you started the timeline and hours of practice at your zero point (1996) instead of halfway through 2009? Or is that less motivating? :)
Indeed it would. And I think a longer squiggle would be *more* motivating. That four months of relatively diligent practice and record keeping show up as that tiny little line is a bit discouraging. :)
The problem is that I don’t have detailed data for anything prior to June 22 of this year, so the line would be formed of straight sections that span whole year periods. Somehow such approximations aren’t as satisfying to me in the graph. Although the squiggle is tiny, if nothing else, it’s an honest representation of daily progress. Baby steps. Baby steps.
Margaret, you’re a great practicer… you should implement a tracking system too!
Hey its jeni thx for a great week of taiko
Love this and love your thoughtful tabulations. It’s surprising that in a year you might only have 316 hours (2001, for instance), less than an hour a day. I’m trying to think of all the conclusions that can be drawn from this: that sustained, concentrated practice is extremely difficult; that “work” is not the same as “practice”–for instance, you could not count a 40-hour work week for fifty weeks a year as somehow 2000 hours towards mastery of your job; how very few available hours there really are in a year; how I’ve got to get cracking at becoming master of something :) , though right now I feel like I’m on my way to being master diaper-changer. Must get some more rest before the next round of nursing, diapering, rocking the baby to sleep gets underway. Way to go, Meat.
Humble congratulations from afar on completing Year 1 of this great experiment. Has your philosophy of practice changed in any way as a result?
Thank you very much for the anniversary note, Margaret! How did you know it’s been exactly a year this morning?! I’m moments away from publishing my thoughts on the last 365 days of practice…
A happy coincidence, I have to say. :)
I’m intrigued that the proportion of what you consider real practice time has shrunk because you don’t count the time you spend generating source material to practise; I wonder if that’s being too purist. Does it make sense to discount the time it takes to realize that one lacks a skill and figure out what practice will develop it, counting only the practice by which one acquires that skill? Aren’t all of those steps essential to progress?
I think intention is critical to progress generally, but what about unintentional skill acquisition? In other words, could you develop skills other than the one you meant to develop while practising? (Or is that just the flip side of acquiring inadvertent bad habits?)
Luckily, running out of obvious technical challenges to focus on is a purely theoretical risk for me for the foreseeable future. :)
Cheers & please keep us updated in Year 2! And please say more about your basic kata philosophy….
Kris Maz…put a link on my facebook page of the family photos of Shasta Yama. Thanks to you both for all of the hard work and play you brought to the performance.
This is incredible. I’ve had the idea of starting up a blog, but the staggering number of 10,000 proved to be quite the deterrent.
Congrats and I look forward to the day you attain the grand title of… Master
Hey I just wanted to note that I recently read the outlier chapter referring to the theory of 10000 hours of practice being the key to mastery in my high school senior english class and then came upon your site here… the whole concept sounds very appealing to me and seeing your progress as an individual working towards your goal is encouraging for the rest of us with dreams and goals. I personally don’t really know much about taiko, and I have never practiced an instrument before today for several reasons, but just learning about this theory and reading about your diligence makes me feels intrigued and challenged. I have been contemplating learning to play an instrument for some time now, and although I am somewhat financially challenged, I feel more inspired to start up a goal such as yours sometime in the near future. Thank You for being a model and inspiration for others and keep up the good work, surely in the end it will pay off.
