【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. We have listed 12 types of chords that are often used in actual songs, from basic triads to sus fours and sixes. The arpeggio shape is also listed, and the 12 keys are arranged in two ways, clockwise (C, G, D...) and counterclockwise (C, F, B♭...) of the circle of fifths, so even those who play popular and jazz music can use it without any hesitation. The double-page spread laminate design makes it easy to carry and can be folded and stored like a restaurant menu! Please feel free to use it as supplementary teaching material for your lessons. ・Print type: Kikubenhen ・ISBN code: 9784285128369 ・JAN code: 4514142128363 ・Publication date: 2010/11/05 We have listed 12 types of chords that are often used in actual songs, from basic triads to sus fours and sixes.
