I have no idea why or how, but recently I was allowed to record a pretty famous pianist. I will not mention his name here in case I might get into trouble for sharing his recording, but his name can be found in the MP3's ID3 tag. Please don't call him by name here.

I've included the entire work as this is something you're going want to hear.

Please critique my work.

Yes, spaced omnis, MKH-80. They were nine feet out, seven feet high, and two feet six inches apart.

Some specific questions:

Does anyone know how to combat a wolfy piano?

Do you think the imaging is to indistinct?

I'd like to improve the clarity in the future. Spearritt thinks this one is too close. I find that it's already getting a bit verby in the LF so i'm wondering how to get extreme clarity with a nice bloom and without feeling like you're inside the piano. Any guidance?

Its one of the holy grails of recording IMHO. Trying to capture that rich brassy bass of the piano while maintaining articulate clarity throughout all freqs and also get sparkling highs.

Somwhere in there you have to have a coincident pr and some omnis. The distances and positioning of these pairs I have been experimenting with a lot recently and have some things worked out.

What do others think?

DavidSpearritt Sun, 11/13/2005 - 05:07

David, have you some favourite piano recordings that you would like to emulate?

Some of mine are:

Murray Perahia, Handel & Scarlatti, SONY
Pogorelich, Gaspard DG
Pogorelich, Scarlatti Sonatas, DG
Maria Joao Pires, Mozart Sonatas Complete DG
Freddy Kemp Rachmaninov, BIS

I used to like most of the Philips sound with Alfred Brendal and Claudio Arrau, but find it a little subdued now and prefer the colder but clearer DG sound. Maybe I am going deaf. :)

Sounds beautifull
I like the fuzzyness of the imaging

Personally I like piano to be a bit more subdued and more room / verbed

I haven't tried this yet, but I'm hoping to do so pretty soon:
Omni's AB fairly far away as main sound, further away than this recording
XY or ORTF (card.) fairly close and only very very soft in the mix, just to add a tiny bit of presence / clarity back into the main room sound

Cheers

Gonna have to listen to this on my good rig (just listened on my laptop- doesn't do sound justice). Anyways, I find the MKH80s are a strange mic to work with. I find that I always need to move them further back than I would expect with any other microphone out there.

When I use spaced omnis on a piano, I also space them a bit further apart and then move the individual mics a bit to compensate for the sound coming off of the piano (more to the left for more high end, to the right for low end, etc... If the high end sounds great and the low doesn't, I may even tilt the right microphone a touch to make it work....)

It is fun to work with great pianists, eh? I recorded Earl Wild a few years back- what a spectacular recital the guy gave. Then to consider his age, it just made it that much more special.

Please, please elaborate. :D I like your recordings very much. In fact, I have your Carmen and Pictures recordings saved to my hard disk and play them back for reference every once and a while. I'd love to hear elaborations on those setups and the things you were thinking when your recorded them.

Why do you believe you have to have a coincident pair? Do you believe the type of clarity and fullness I want is not possible with a single pair? I've often wondered how necessary more mics is for a single instrument, and i've come to the temporary conclusion that they are superfluous. I'd love to hear about the reasoning behind more mics on piano.

Again, i'd love to hear more. :D

Thanks so much for spending the time on me!

And thanks GentleG for your input as well!

David French Sun, 11/13/2005 - 10:42

Ben, just saw your post.

I totally agreee about the MKH-90 distance thing. Other mics (4006, 183) had been swamped at nine feet, but not these mics. Odd, huh?

So, you space them even farther apart? Last time I tried that, it was an imaging snafu? How in the hell do you pull it off? I've had two little pools of mono in each speaker with this approach. two and a half feet was the limit on this recording. Still the imaging is a bit vague IMO. Please please share a recording you've done with just a single widely spaced omni pair. Also, why do you choose an omni pair over things like Spearritt is talking about?

FifthCircle Sun, 11/13/2005 - 11:09

I don't go a whole lot wider than 2.5' but I do go a bit.... (probably more like 3 or 3.25 feet).

I find that for sessions, I don't use just a single pair either... I usually have a regular pair with a pair of outriggers (omnis) to open the sound up a bit. For concerts, I go with just a pair that depending on the instrument, player and room is either a 426/SF-24 in some sort of blumlein or M-S setup, or a pair of spaced omnis.

When I use just the spaced omis, I use two mic stands so that they can be moved easily. I usually place them so that the mics are "looking" just over the top of the lid- not into the instrument. With my B&K's, I usually place them about 6 feet out or so (perhaps a touch further out depending on the room). I find that when positioning the mic looking into the instrument that it can become rather mid-rangy or woofy sounding. Capturing a bit less direct sound can help smooth it out.

Another trick when recording pianos that are really nasty (or when doing concertos with orchestra), is to place the microphone fairly close in (a couple feet out) and low down facing the lid to capture all first reflection sound from the instrument. It can smooth out a harsh top end and save a recording. In a concerto, it also gives you a sound that is a bit closer to what the audience will be hearing in the hall.

It has been a couple months since I've done a piano recital.... Next one I do, I'll happily send you an example.

I've got a piano session going on right now, but I'm not using spaced omnis for it... I have an ORTF pair of my Sankens, Schoeps MK21's as flanks (spaced way too widely, but they are flown in the hall and I can't move them closer), and a pair of KM130's as ambience microphones in the back of the hall.

David, I am not going to give you measurements or rules to follow because there are none. Here are some of my observations:

1. Spaced omnis on their own seem to rarely produce a satisfactory result. They often sound woofly and always sound image confused to my ear.

2. If they sound woofly, you are too close, try moving back 30cm at a time until the ratio of direct to reverb sound is "correct", ie not woofly. :)

3. A coincident pair seems never woofly and can provide the clarity and central image that solves the omni problem of the lack of clarity, but I still like omnis as outriggers for the LF extension and to add richness to the room sound. Even though the term outriggers implies wide spacing, sometimes I use 400mm on one stand.

4. I have tried omnis both close to the reverb radius, ie behind the coincident pair and in front of the coincident pair.

5. Behind seems to get a great room sound, but adds little to the main image.

6. In front and positioned so both pairs get the same direct/reverb ratio is often the best. The theory says the coincident pair can be 1.7 times further back than the omnis, but in practice I find this puts the coincident pr too far back.

7. I start with the omnis looking down at the soundboard, positioned just below the plane of the lid, ie avoid the first reflection. Adjust from there.

8. I find the blumlein pair is best lower and horizontal or slightly angled, picking up the first lid reflection and avoiding floor reflections.

BUT, there are no hard and fast rules and in all cases, you have to use your ears to adjust and make mods before deciding its all OK.

Recently I have purchased a pair of MK21 caps and these have produced the best sound I have experienced as outriggers, having used 4003's, MK2s and KM130's. The AKG426 is probably the best central mic I have used, closely nipped in the heels by the SF24.

David, I can vouch for both Dave and Ben's approaches, there's not much I would add or change to their suggestions. (Ben, your approach has always been surprisingly similar to mine. Are you sure we didn't work together somewhere in a past life? ;-) )

Instead of beating yourself up, I would remind you that so very much of the end result depends on three things: The sound of the room itself, the quality of the instrument, and (more than people realize) the artistry of the musician. So many times during a "bad" recording, I will suddenly find my own "alarm bells" going off, and snap to attention, heart racing, wondering what's gone wrong, what's happened to my gear, or what "I" did wrong. Some day's it's a general feeling of doom and gloom, etc. .....only then does it hit me: It's the artist (as such!) messing up.

As many of us are musicians as well, you may know what I'm talking about: there is one set of alarm bells that goes off for bad audio, and another similar alarm system that is triggered when bad notes (or just bad musicianship) happens. Sometimes when one is drifting along listening to the music in cans, etc., we can be snapped by to attention by one of these alarm bells, only to find out it's NOT the gear, it's the musician!

When THAT happens, all the great mics and room sound doens't help a bit. Of course the opposite is very often true as well, when the magic happens, and all the parts gel; suddenly you've got a jewel on your hands. You can't always predict these things, you can only do the best you can, and be ready when it does happen.

Thanks Ben.

Pretty simple actually...

I'm doing the session at a hall with an installed system. (I'm a staff engineer at this place). They have MKH80's and the Schoeps installed going through Millennia Pres. The ambience mics are also installed. All installed mics have a pulley system to move them, but it is tough simetimes to get them in exactly the position you want.

I want to be able to move the mains more to my liking so I used my Sankens going through the Pacifica (which I left on stage). The ORTF pair is still the main pickup. The flanks that are hanging are basically mics to make the image a bit wider and open things up a bit. I can't use too much of them, though, because they are spaced quite widely. Lastly, the ambience mics are being used because it is a pretty darned good sounding hall and if I can avoid digital reverb, I'd like to... I bring in the ambience mics like a reverb return. I can't use them in concerts because they pick up too much audience noise and too much air conditioning noise.

JoeH Mon, 11/14/2005 - 09:49

I've used as many as seven on a few serious piano recording projects. (Hey, I like choices in post! ;-) )

Two main cardioid ORTFs (or omni's) close-in, piano at full stick, mics on one stand, looking over the crook, above the case, standard stuff.
Two spaced omni's (2-3' apart depending) roughly 10-15 feet out and as much height up above stage level.
Two "house/ambient" omni's mid to halfway back in the hall (for the same stated reasons as Ben: I like real reverb IF it's there, instead of dialing it in with software.)

The seventh mic is the joker in the deck: it's on the low end/bass strings, set at the tail of the piano, looking up across the length of the instrument to the player, and only necessary when the client wants something more down there, esp if we need a little help with the bass management on 5.1 and 2.1 mixes. (It HAS made a difference on a few things we've done for truly picky clients.)

Granted, the above setup is a bit much and often overkill for most cases, but for surround mixes (and we've done several as described above with cello and a Bosendorfer piano accompanist), it's a beautiful, flexible approach for a gorgeous, "you are there in the front row" 5.1 sound.

The "downmix" to stereo of all these mics can work if you're careful and don't overdo it. Of course, there's nothing nice than just TWO well placed mics if everything else is in its proper place in the universe.

This is an amazing thread, better than any book on recording
techniques! I've been trying to calculate a good combination of one
stereo mic and two matched omnis to purchase for recording piano solo and piano/violin duo, which is a difficult and expensive decision to make. I was thinking a pair of Sonodores for the omnis and either an AEA r88 or AKG 426 as the stereo mic. I'm impressed that both Ben and David S. tend to use the AKG for their coincident pair.

I too can vouch for these techniques. I am quite fortunate to record piano on a fairly regular basis (both in the studio and on location at various venues ranging from a small lively church to Music Hall - piano with the Cincinnati Symphony Orchestra).

Having a wonderful piano and a wonderful room to work with are gifts. When one or both are not there, it can be frustrating, or as Joe put it, doom and gloom, to get a decent sound. I am quite fortunate to also have probably one of the finest piano's within hundreds of miles in my studio as well (no joke!). I have had several pianists come in and say they would have to go to NYC or Chicago to find one as refined. The piano is a fantastic sounding Steinway Artist Series Concert Grand - which used to belong to the late Bill Black. It is originally from NYC and was one of the piano's used for recording sessions and major concerts in NYC not too long ago. Having it in the Corbett Studio is truly a blessing. For the past year, I have had the opportunity to try out different microphone techniques and am now using the SF24/omni combo quite often. Once things are setup....I hardly have to do a thing, just add a little convolution reverb (it is a dryer studio after all) and edit, and I am done. When Eugene Pridonoff was in about a month ago, it took me less than 20 minutes to get it to sound beautiful. Now I am trying some other techniques to harness the sound for more jazz and popular applications. If I have an artist that allows for it, perhaps I'll post something for you folks to listen too.

I am not able to do that with the CSO recordings, for obvious reasons, but I they have their piano there tuned and conditioned to be bright (a bit harsh up close) so it projects over the orchestra throughout the hall. Therefore, when I need to get a little more warmth out of it...I will mic it with a modified SM69 FET or SF24 from in front edge of the stage, a foot or so above the floor pointed up at the lid. The microphone is a few feet away from the piano at best. This combo (with the appropriate digital delay set) gets some of the first order releftions and allows me to warm the tone of the instrument up a bit as well as balance the instrument with the orchestra, as the main orchestra microphones are a tad higher than ideal for capturing the piano. That said, every once and a while, they'll have the piano set upstage just right, so my main mic array captures it wonderfully. If it is the older piano (which isn't as bright), then I don't have to do anything. However, the pianists like the action of the newer piano more.

David - since you are just over the state line in Indiany and are really not that far away (and I have folks from Bloomington and Indianapolis coming to use the piano anyways), you are more than welcome to come by and hear, listen and try out microphone techniques on our piano here in Cincinnati. Same goes for hearing the CSO recordings live too if you wish. Just email me off of the studio web site. I am more than happy to share and learn as well.
