Features: Tap and Glow: Harmony app is very easy to play: take the line as a reference to tap the squares and mirror the music notes. The squares will glow when you tap on them! Anxiety antidote: The relaxed melodies created on Harmony are perfect to kill anxiety or OCD problems. In fact, Infinity Games are known for slowing a player's heart rate after 10 levels played. Free of timers and other stress features, this game feels like a yoga session in paradise! Different instruments: There are several instruments available on Harmony. You start with a piano, but you can go for a different melody later if you prefer wind instruments or string instruments. Music, Maestro: Tapping the squares on the right tempo is the only thing you need to create smart music on this calm and minimalist IQ test. Can you play with different instruments? Just like paradise: Like a mirror of relaxing sounds, the Harmony app provides you a calm IQ test to feed your soul and tease your brain. You must get the same look on both sides of the line. Just tap the right polygon and the shapes will glow! Boss levels: Besides the classical music and the tacit IQ test present, the boss levels featured on the Harmony app will relax your soul! Check how many relaxed melodies can you create during a boss level! Music, Maestro! Harmony: Relax Melodies is a smart music game reminiscent of a guitar hero, where you must reflect the music notes by tapping the free squares. To be successful, you need to take the white line as a reference and create asymmetry. You will finish some levels in a heartbeat. Others will demand more concentration. Each tap will produce a minimalist melody, providing the illusion you are a real maestro! Like a guitar hero, you will feel like a real musician in paradise when you tap the music notes on the right tempo. The major difference between guitar hero and the Harmony app is the classical music: the relaxing sounds featured in the game are calm and minimalist. Playing Harmony is very easy: just reflect each polygon and the symmetry will glow. If a polygon is three spaces on the right, you must tap an empty polygon three spaces on the left. Once you reflect every symmetry, the squares will glow, and… it’s done! By tapping the music notes on the right tempo, you will be the maestro of relaxing melodies. Merging the brain exercise of an IQ test and the slow heartbeat of a yoga session, we could say you are smartly relaxing. Just look at it as a mirror: your brain will be pleased for each melody you reflect! The chapter names are based on classical music composers – like Sibelius or Vivaldi – and each chapter has its own relaxing sounds palette. Each chapter will bring a different polygon, melody, and symmetry. Your soul will rejoice with the 24 different relax melodies and more than minimalist 1000 levels! Vivaldi built his legacy with the Four Seasons, you can start yours with Harmony! Feel free to activate your guitar hero mode and tap the music notes as fast as you can! Go from mid-tempo to up-tempo! Music, Maestro! The smart music combined with a calm IQ test will create a paradise environment. Players who suffer from anxiety or OCD problems praise our games. The Harmony app works as a yoga class and will keep you calm, slowing your heartbeat. The relaxing sounds and the guitar hero gameplay will numb your soul and help you deal with anxiety or OCD, while you become a classical music maestro. Harmony: Relax Melodies is a smart music odyssey through an abstract and a minimalist paradise, where tapping a polygon and reflecting asymmetry is all you need to do to get rid of anxiety or OCD symptoms.
