Learn Maya Numbers vs PlayPiano Smart Practice Coach

Both, the Maya numeral system and decimal numbers are positional or place-value notations. There are two major differences: 1. In the decimal system each numeric position has a value that is a power of 10, whereas in the Mays numeral system each numeric position has a value that has a power 20. 2. In the decimal system place values increase from right to left, whereas in the Maya numeral system place values increase from the bottom to the top. This app simultaneously displays user generated Maya numbers and their equivalent decimal values at each place value, as well as the final decimal equivalencies for Maya numbers 1 to 1,279,999,999.

PlayPiano listens while you play real sheet music and grades every note as it happens. Stop, and you get a score you can trust and the exact bars to work on next. Free. No subscription, no ads, no account. Works with any USB or Bluetooth MIDI piano keyboard, and with the on-screen keys when you have none. PICK WHY YOU ARE HERE Tap a piece and choose the session before it starts. Play is yours: every setting unlocked, nothing scored. Coach hands the piece to its practice plan, which picks the passage and the exercise. Grade is one run under fixed conditions: both hands, nothing waiting, ordinary timing, and it counts. The screen says which it would pick, and shows your best score and its trend. NOT A VIDEO LESSON Open a built-in piece or import your own MusicXML or MIDI. The score is engraved like a printed edition and scrolls as you play, and each note lights up right, early, late or missed. A REPORT THAT TELLS YOU WHAT TO DO The review opens on the weakest part of that run and a button that loops the bars which lost the most. Open Breakdown for all seven components; tapping one repaints the score by it alone, so a chord score of 62 turns into bars you can see. A SCORE YOU CAN TRUST The grader measures what a piano teacher listens for: right notes, timing against the beat, note lengths, dynamics from the written marks, how together your chords land, evenness, and pedal. A score is only awarded under the same conditions each time, so a 94 today means the same as a 94 next month. A PRACTICE PLAN MADE FOR THE PIECE Give the app a piece and it reads every bar and writes a plan: short passages in the order a teacher would take them, each with one job. Hands separate. Slow. Broken chords blocked into shapes. Every chapter ends with the passage as written and scored, so you are measured on music, not drills. One new piece a week, and the score file never leaves your device. PRACTICE TOOLS THAT DO THE WORK Wait mode holds the music until you find the right key. Loop any passage by dragging across the bars. Take it up raises the tempo after a clean pass and drops it after a weak one. Switch a hand off and the app plays it while it scores the other. A METRONOME BUILT FOR THE MUSIC STAND Time signatures from 2/4 to 12/8, subdivisions and swing, a tempo trainer, and silent bars to test your pulse. Inside a piece, the click follows the score's own meter. A GUIDED PATH FOR BEGINNERS Fifty-one short units: finding notes, five-finger position, chords, scales, reading, key signatures and your first real pieces. Every unit is passed by playing, not watching. Already play? Skip ahead, or test out of a chapter. TRAINERS AND SIGHT READING Seven trainers: note reading, chords with inversions, scales in both hands, rhythm, interval and chord hearing, and echo. Levels open as you play clean rounds, and what you miss comes back until it sticks. Sight reading gives you a fresh four-bar piece every time, at five levels. Home opens on Today with your next step, Practice holds the trainers and tools, Library holds your pieces. Landscape, with a full-width keyboard, on iPhone and iPad. Your progress stays on your device, and anonymous reports can be switched off in Settings and guide.
