The TomTom 340TM has the perfect sized screen *(not too big, not too small). The lifetime traffic and maps are great. Saves time in my taxi because of the traffic service it has.

Press the START/STOP button to start play of the rhythm.
When you do, the selected rhythm starts to sound.
Accompaniment keyboard Melody keyboard
The entire keyboard can be used for melody play while the POWER/MODE selector is set to NORMAL.


Using the CASIO CHORD system
The CASIO CHORD system lets you easily play the four main types of chords. Play of chords is simplified as shown in the chart below. Keys Type C (C Major Chord) Cm (C Minor Chord) C7 (C Seventh Chord) Cm7 (C Minor Seventh Chord) Example

Step 1: Master the timing
Pressing the ONE KEY PLAY buttons plays the melody for an auto-accompaniment tune or the right hand part for two-hand tunes. In both cases, the autoaccompaniment (the left hand part in the case of twohand tunes) is played automatically by the keyboard. In place of the ONE KEY PLAY buttons, you can also press any key of the keyboard to play the melody or right hand part. The purpose of this step is to familiarize yourself with the timing required to play melody notes.
To play a built-in Song Bank tune
Look up the number of the tune you want to play in the Song Bank list. Press the SONG BANK button until the SONG BANK indicator appears.
This causes the number and name of the currently selected Song Bank tune to appear on the display.
Step 2: Master the melody
In this step, you use the display to learn which fingers you should use to play, and the key light system to learn which keyboard keys to press. You can play at the pace you want, because the auto-accompaniment or left hand part waits until you press the correct key.
Input the two digit number for the tune you want to play.
Example: To select 13 TWINKLE TWINKLE LITTLE STAR, input 1 and then 3.
Step 3: Play at normal speed
At this level, the keyboards keys still light to indicate which notes to play, but they no longer wait for you to press the correct key. The auto-accompaniment or left hand part is played at normal speed.
Press the START/STOP button to start play of the selected tune.
The tune you select plays repeatedly, with the keyboard keys lighting to indicate the melody notes.


To stop Song Bank tune play, press the START/ STOP button again. To exit the Song Bank Mode, press the SONG BANK button again.
When you do, the SONG BANK indicator goes out.
Crossed Finger Indications
The display also shows when you have to cross fingers to play notes, and in which direction your fingers should cross. Example: Display for playing the notes below with the right hand
Always enter two digits for the Song Bank number. You can input a Song Bank tune number even while another Song Bank tune is playing. If you input the wrong first digit for a Song Bank tune number, you can return to the previous setting by pressing the SONG BANK button. The RHYTHM button is disabled in the Song Bank Mode. If you want to play a rhythm, press the SONG BANK button to return to the normal mode first.

Key Lighting System Operation and Display Contents During 3-step Lesson Play
Whenever you select an Auto Accompaniment tune (00 to 83) for 3-step lesson play, the key lighting system shows you which keys to press, while the display shows you the fingerings.

Voice Fingering Guide

Voice fingering guide uses a simulated human voice to call out fingering numbers during Step 1 and Step 2 one-hand part practice. If you need to press a key with your thumb, for example, voice fingering guide says, One! In the case of a chord to be played with your thumb, middle and little finger, voice fingering guide says, One, three, five! Voice Fingering Guide calls out fingerings only when you do not press the proper key when you should.

Note Pitch

The keyboard key that should be pressed lights. The fingers you should use to play the notes are also shown on the display.

Note Length

Keyboard keys stay lit for as long as the note should be played. The fingerings also remain on the display for the length of the note.
To turn voice fingering guide on and off
Use the SPEAK button to turn voice fingering guide on and off.

Next Note

The keyboard key for the next note to be played flashes, while a number appears on the display near the finger you should use to play the next note.
Voice fingering guide indicator
Series of Same Pitch Notes
The keyboard key light turns off momentarily between the notes and lights again for each successive note. The fingerings also turn off and back on again. Example: When play requires pressing keys with fingers 3, 2, and then 1
1st Note Next note Current note 2nd Note 3rd Note

Timing Indicator

The timing indicator helps you become familiar with tunes you are playing for the first time by indicating the timing of notes you play on the keyboard. Timing is easier to see when you use a slow tempo during lesson play.

To change the tone used for the melody of a Song Bank tune
Following step 3 of the procedure on page E-21, press the TONE button.
Both the SONG BANK indicator and TONE indicator appear, along with the tone number and name of the tone that is currently assigned to the keyboard.
Try pressing any one of the keyboard keys in place of the ONE KEY PLAY buttons.
Pressing any keyboard key plays the correct melody (right hand part) note. Pressing more than one key at the same time counts as a single melody note. Pressing a key while another key is held down is counted as two melody notes.
Input a value to select the tone you want to use.
Selecting another Song Bank tune switches the tone setting to the newly selected tunes preset melody tone. The tone assigned to the keyboard is the same one specified for the melody of the Song Bank tune. The above procedure can be used to change the Song Bank melody tone before starting play or while play is already in progress. You can also change the tone of two-hand tunes (tune numbers 84 to 99). Note however, that selecting a sustainable tone (like an organ tone) when using 3-Step Lesson Step 1 or Step 2 (in which accompaniment waits for correct input from you before proceeding), can cause notes of the auto accompaniment to be sustained while the keyboard is waiting for your input. If this happens, play something on the keyboard to stop the sustained note.
The correct note is played even if you do not press the key that is lit.
To stop play at any time, press the START/STOP button.
When you do, the STEP 1 indicator goes out.


Press the STEP 2 button.
When you do, the STEP 2 indicator appears. After a count sounds, the keyboard stands by and waits for you to play the first note of the tune. If the tune includes intro measures, the keyboard enters standby after the intro measures are complete.

Press the STEP 3 button.

When you do, the STEP 3 indicator appears. Play starts after a count sounds.
Play along on the keyboard, following the keys as they light.
The accompaniment (left hand) part of the tune plays at normal speed, regardless of what you play on the keyboard. With an auto-accompaniment tune, the keyboard key that corresponds to the next note to be played flashes, and lights when the note should be played. With a two-hand tune, the applicable keyboard key remains lit as long as its note plays. In this case, however, the key for the next note to be played does not flash. Keys light when their notes start to play.

To turn on LOCAL CONTROL/To turn off GM mapping
While in any mode besides the Song Bank Mode (indicated when the SONG BANK indicator is lit), hold down the RHYTHM button and press the SONG BANK button.
Use the TEMPO button ( ) to turn on local control.
This also turns off GM mapping.
