📝 About this app
For musicians from pros to beginners, whether you sing, play a brass, woodwind or stringed instrument or any type of guitar, this app provides a set of feature-rich practice tools that gives fun and rewarding feedback. It’s much more than just a tuner!
So what makes the TonalEnergy the best selling music practice app?
• It's an all-in-one app, with a state-of-the-art tuner, an advanced metronome, dedicated orchestral strings and guitar tuning page, a piano keyboard, sound analysis pages, and audio/visual recording capabilities.
• It’s easy to use. Options like the Target Tuner or Pitch Tracker are on all the main pages. TonalEnergy helps users create rewarding and attainable goals during a rehearsal or when working alone. Colorful analysis data pages and audio/video recording features enhance the experience of practice.
• The metronome is cutting edge. It offers unmatched flexibility in sound choices, tempo settings, meters, subdivision patterns and visual displays. Voice count-ins, the ability to create and edit preset groups and Ableton link for syncing multiple devices make this a superior tool for performers.
• Ear training possibilities are endless. The high quality multi-sampled instrument sounds for symphonic instruments are unique among all other tuning applications. Listening skills can be developed through the use of the eight-octave keyboard, chromatic wheel and tone generator. There are no other sounds like these.
• Learning is a social activity. Using features unique to the TonalEnergy Tuner, data can be collected, reviewed, edited and shared with others. Feedback is essential for growing and developing great performers. It’s all about connectivity.
Chris Coletti, member of The Canadian Brass, sums up TonalEnergy by saying,
“TonalEnergy is a must-have for any serious musician. It's a full suite of tools in one app; the tuner, tone generator, recorder, metronome and beautiful interface make it one of the best tools for musicians out there, period.”
