A full piano has 88 keys. A music keyboard can have more or fewer keys than that, and the portable keyboards below each have 61 keys. Count the keys before you buy, and match the count to the range of notes you play.
The full piano count: 88 keys
A full piano keyboard has 88 keys. The 61-key keyboards below list 61 keys in the size and the title, so the count is plain to see before you buy. A keyboard with 61 keys leaves out the lowest and highest notes of a full piano, and that is the trade for a shorter board.
What 61 keys gives you
A 61-key keyboard has 61 keys, and the 4 keyboards below each list that count. The Casio lists 400 tones and 77 rhythms, the Best Choice Products set lists 255 timbres and 255 rhythms, the JIKADA lists 300 tones and 300 rhythms, and the MIZAYI lists 100 tones and 100 rhythms. The count of keys stays the same across the 4, and the tone and rhythm counts are the figures that differ.
How to read the key count on a listing
Read the size field and the title for the key count. The Casio, Best Choice Products, JIKADA and MIZAYI titles and sizes each say 61-key. A headphone jack lets you play through headphones, and the Casio, the Best Choice Products set and the JIKADA each list a 3.5mm jack.
Power and weight
The Casio runs on batteries and weighs 7.3 lb, the Best Choice Products set weighs 17.2 lb, and the JIKADA weighs 21.8 lb. The JIKADA runs on a power adapter or batteries, and the MIZAYI runs on a power adapter or 4 AA batteries. Check the weight and the power source before you buy.
