Set Review ➟ 21323 Grand Piano
Within the LEGO® Ideas theme, today we present the latest set, reference 21323, the Grand Piano. A set consisting of 3662 pieces with which we will recreate an elegant grand piano.
The first impression you get is that it is a big, heavy box with a very elegant design. Curious to see 18+ printed on the box when in the online shop if you buy looking for age they put it in the section of over 12.
When you open the box, you find another black box, which shows the keys of a piano and in which we find more bags with pieces and instructions. In total there are 36 bags numbered up to number 21.
We start the assembly and the first thing we are going to build is the soundboard of the grand piano. As you build, you realize that the dimensions of the piano will be very large.
This is where we are going to set up the mechanism that will perform the pianola function through the Powered Up app.
We install the motor and connect it to channel A of the Hub, then the motion sensor that will be connected to channel B.
The pianola will be made up of different technic pieces, inserted in an axle and distributed in such a way that as it turns, it will make the keys move and these in turn, move another axis and will cover the movement sensor, creating the corresponding note in the mobile app.
We then assemble what would be the percussion mechanism and the damper rods, which will allow the movement of the dampers.
Next we build the harmonic table and the frame where all the Hose pieces will be connected, which are in charge of representing the piano strings. We will use a large number of " Tile Modified 1x1 with Open O Clip " pieces to anchor the strings.
Then we start to make the keyboard and pegbox bed. This is where we will place the keyboard that we can take out and put in whenever we want.
The result is quite good, achieving a great level of detail, with the characteristic holes of the frame.
Little by little we are giving it the round and elegant shapes of the piano.
It is time for the 3 pedals of a grand piano: left pedal (unicord, a corda or celestial), right pedal (resonance), central pedal (sostenuto, tonal or central). The right pedal will be connected to the damper rod system, which, when activated, will allow movement, making the whole piano more realistic.
Next we will build the 3 legs. These will have a wheel that will allow us to move the grand piano.
Finally we come to the keys. Practically all modern pianos have 88 keys, 36 black and 52 white, ours will have 15 white and 10 black keys.
The construction of the keyboard will be divided into 4 groups and will be the most repetitive part of the whole assembly.
The final result will be quite realistic, you can see that details have been taken into account such as the rocker points, made with the " Ice Cream Cone " piece and that it will allow us to move the keys when we press them. For the hammers, with pieces such as "Brick Modified 1x2x1 1/3 with Curved Top", "Hinge Cylinder" and some "Plates", a great level of detail is achieved.
The next step is the keyboard cover. In this part, we highlight the piece "Tile Modified 2x2 Inverted" with the LEGO pattern screen-printed in gold.
The assembly of the lectern will allow us to put the "PLAYDAY" score by Donny Chen, the author of this set, silkscreen printed on a "Tile 6x6" or the phone itself to use the Powered Up app.
The next step is the construction of the main cover, which is kept open using a system of "Axle" parts
To finish off, we will complete the set with the classic stool-type piano bench with adjustable height. A system of technic pieces and gears will allow us to be able to adjust the height of the bench, giving a touch of realism and detail that would not have been achieved with the simple construction of a fixed bench, in addition to the detail of the upholstery, achieved with the "Plate Round 2x2 with Rounded Bottom"
MUSIC
This set combined with the free LEGO® Powered Up app, will allow us to "play" a piece of music or activate the automatic performance mode.
Once we open the app and connect to the HUB via Bluetooth with our mobile, we have 2 options: Listen or Play.
Listen
With this option, we can choose between 10 musical pieces
After choosing the piece, we hit play and see how the musical notes of the piece in question are marked on the screen of the mobile phone as the music plays.
On the piano, the pianola will be in charge of moving the keys as the music plays.
Play
For this option we can choose between 5 musical pieces.
With this option what we will achieve is that once we press a key, it raises an axis with some "Technic Liftarm 1x2 Thin" at one end, which will be responsible for covering the motion sensor, triggering the music on the mobile phone.
No matter which key we play, the notes will be played in the order shown.
The final result is a piano measuring approximately 22.5 cm high, 30.5 cm wide and 35.5 cm deep, with a very elegant design.
The curved shapes of the piano, the keys and being able to use them, the details of the interior of the piano, the lectern, the piano lid, the bench with its padding, are all details that bring this set to a high level of realism and detail.
The building experience is pleasant and interesting. As you build, you can learn in broad strokes, what a piano looks like and the parts it consists of, so it can be an instructive set to learn a little about this great instrument.
The only part I didn't like is the cover that closes the interior where the HUB is located. When closing this lid, there is a space left that breaks a little with the whole design. To solve it, I have chosen to add some "Tile Modified 1x3" Inverted with Hole".
