LCD needle meter with wide measurement range from C1 to C8 and good response. The wide measurement range from C1 (32.70 Hz) to C8 (4186.01 Hz) enables easy and accurate tuning of low-pitched instruments, instruments with many overtones that are difficult to pick up, and acoustic instruments such as guitars and ukuleles. The LCD needle meter, which uses Korg's proprietary technology to accurately detect pitch without time lag, also allows you to check the shaking that tends to occur with long tones on wind instruments, helping you to develop a stable, unshakeable pronunciation.

The transpose function is useful for transposed instruments where the actual note played differs from the note name written in the score. In addition to the usual in C, it is now possible to switch between in F, in B♭, and in E♭. This makes it possible for beginners to play correctly while looking at the score.

In an ensemble, such as a brass band or orchestra, harmonies of third intervals are easily perceived as out of tune, and can be made to sound better by slightly adjusting the pitch to a pure major or minor third. The TM-70T's meter scale provides marks that indicate pure major and minor thirds, and simply by tuning so that the needle coincides with these marks* allows you to play in beautiful harmony with an ensemble. This is convenient not only for orchestral instruments but also for vocal music or acappella practice.

* When tuning to a pure major or minor third, the specific note to be adjusted depends on the music that you're playing.

In addition to a meter for visual tuning, the TM-70T provides a sound out mode that lets you tune using your ear while listening to a reference tone from the internal speaker or a set of connected headphones. The reference tone can be selected from the three-octave range of C3 (130.81 Hz) to C6 (1046.50 Hz), supporting not only wind instruments, but also a variety of other instruments.

Sound Back mode generates the reference tone that’s closest to the pitch that you’re playing, while simultaneously indicating your input pitch on the meter. Since this allows you to check the pitch with both eye and ear, it lets you tune more precisely, and it’s also ideal for ear training. Refining your ear is a particularly helpful practice method for the beginner.

You can set the tempo using three different methods:

• Pendulum Step: this lets you increase or decrease tempo values in the same way as on a standard pendulum-style metronome
• Full Step: here you can specify the tempo in single-step increments in the range of 30 to 252
• Tap Tempo: with this setting you can specify the desired tempo by pressing the switch in time with the song you're playing

There are 15 different built-in rhythms, including:

• Time signatures 0 through 9
• Duplets, triplets, and triplets with middle note omitted
• Quadruplets and quadruplets with the middle note omitted
• 30 to 252 bpm
