For Piano Practive
The piano produces colorful, dynamic sounds spanning the range of an entire orchestra, with rich tones across seven octaves and touch sensitivity from delicate pianissimo to powerful fortissimo. However, because of the instrument's large structure, the player always hears the piano differently from the audience.

With the CD-2u/SD-2u, you can record your practice and performances from the audience perspective, allowing you to check exactly how your playing sounds to your listeners. This ability is useful to both players and piano teachers.
Tips for recording: Piano
The sound of an acoustic piano comes from two elements: the vibration of the strings after they've been struck by the hammers, and the vibration of the sounding board as it resonates along with the strings' vibrations. It is the blending of these two elements that creates the unique and beautiful tones of the instrument.

To record the sounds of a grand piano, place the CD-2u/SD-2u near the concave portion of the curve on the piano's body. Then, adjust the recorder's distance from the piano to control the brightness of the sound to suit your taste. Moving the CD-2u/SD-2u closer to the piano will capture a sound that is brighter and clearer, while moving the recorder farther away will capture a richer and mellower sound.

The height of the recorder also influences the balance of the sound that’s captured. Using the piano’s upper rim as a reference, place the recorder higher to catch more sound from the strings, and lower to catch the sound of body resonances.

From your playing position, you can easily control the recording functions on the CD-2u/SD-2u with the included remote control.

When recording an upright piano, the sound basics are the same. Open the top lid and place the CD-2u/SD-2u about one to two meters away from the piano. Start with a height of approximately one meter, and then adjust the position to capture a sound balance that you like.
Using the CD-2u/SD-2u for personal practice and lessons
Record your playing and listen back instantly.
As you play the piano, the sounds you hear and that audiences hear are not same; to listen objectively, it's important to record your playing from the audience's position.

With the built-in, high-quality stereo microphone in the CD-2u/SD-2u, you can record your performances easily without any setup hassles. After recording, play back your performance through the onboard speakers or headphones to evaluate every nuance, including interpretation, dynamics, and rhythmic accuracy.
Audio Example
Audio Example
Slow the tempo to learn passages and analyze music in detail.
Master difficult passages by using the Speed Change function on the CD-2u/SD-2u. Play back professional recordings at a slower tempo to analyze performances, and then record your own. You can play your recordings at a slow tempo as well; this helps you to hear weaknesses or bad habits that you may not be aware of as you play.
Video Example
Play along with popular songs.
With the CD-2u/SD-2u, you can play along with accompaniment from popular music on commercial CDs and WAV files. The Key Change function allows you to instantly transpose any song into an appropriate key for piano without reducing the sound quality. If you like to sing, you can use Center Cancel to reduce the lead vocal in commercial songs and sing the part yourself!

Create a professionally recorded CD for auditions, contests, and lessons (CD-2u only).
With the CD-2u, it's simple to make audio CDs for auditions, contests, and other uses by recording directly to convenient CD-R/RW discs. If you're a music teacher, you can make custom CDs of lesson materials, example performances, or right-hand-only/left-hand-only performances, providing custom material for students to take home and practice with.
