Just started piano lessons? Or maybe you picked up that cool looking headless guitar from an auction site and surprise, it's a baritone and in D! Or perhaps you've been playing violin for a while, but that new piece has you wondering about the harmonic minor scale. And if you picked up a mandolin this time instead of yet another guitar, you certainly want to see how your favorite pentatonic is played on that slim fretboard. Starting out can be rough, but learning continues as our interests evolve and that is fantastic. ScaleMaster is your go-to companion for learning scales on your instrument, and no matter how we look at it, scales will remain an essential part of our musical journey as beginners or professionals. Seeing any scale in music notation and on your instrument at the same time is pretty cool. No need to translate between the two. The notation shows you what to play, and your instrument shows you where your fingers go. Whether you're just starting out or need a quick reference, it's all right there. As you practice, you'll want to speed things up, slow them down. Maybe you've got your fingers organized after a couple weeks of working that harmonic minor mode, or you're working through a tricky passage. Adjust the tempo and keep pushing yourself. Save your scales too, that E Blues scale you've been working on, the exercises for your band's repertoire, or the scales you're exploring for that chord progression that keeps showing up. Each scale document remembers your instrument and where you left off. And that includes positions because for some of us an F Mixolydian scale looks very different in 5th position than it does in 3rd. But as for help with improvising, this is where ScaleMaster really shines. That Bbm7b5 chord keeps coming up, and you're tired of that same old scale. So, find the scales that work. Hear how they sound, and flip back and forth between different possibilities until something clicks. It's not about memorizing every scale, it's about discovering the ones that speak to you and expanding your vocabulary when you need it. If you're a pianist, you get a full 88-key interface. Guitar players get the 24 frets they want. String players can set custom tunings, that detuned E string on your violin, your new five-string banjo, or that Open D tuning for that one song. And when you're ready to work on reading music, switch clefs and practice with the same scales you know by ear. It all connects. • Over 200 scales from around the world • Scale visualization for your instrument in music notation and schematic • Reference instruments: piano, guitar, bass, banjo, mandolin, violin, viola, cello, double bass • Scale documents recording instrument, position and more for current and future reference • Universal transposition of any scale or exercise • All common clefs for reading practice • Dozens of tuning presets There are two main pillars to ScaleMaster Pro - reference and play. Finding good scale options for that old major chord is one thing, evaluating their sound another. For that you can generate scale patterns, change their tempo, key and sound to get a taste for what fluency would get you. Reference - as in reference instruments, alternate tunings, sound and notation alternatives and more. Playing along on the other hand is foremost excellent practice. You can slow things down or crank up the speed - ScaleMaster shows you where the notes are and play along if you want it to. Scales are a central topic for us musicians with many periods of interest. For a while we're into pentatonics but then get caught up in blues scales, church modes, exotic scales and more. ScaleMaster helps keep track and lets you sound things out.

The BlueScalesTrainer was created by good motivation targets for 2019. Not loosing weight this year, but finally know where notes are on which fretboard position on my guitar to play solos. Like everywhere, this require a lot of practice and I started direct in the AppStore looking for suitable apps. Although there is a lot dealing with Scales, it is either too much, visually too small and often not helpful for practicing. The features I missed are now available in the BlueScalesTrainer: * The scales should be displayed while playing, so it needs a music audio player * New songs should be analyzed because I'm not able hear the key of a song * The scales should then be displayed individually in large size and as an overview, matching the selected song * Overview and single view of scale patterns should be switched by foot pedal * A fretboard view provides a complete overview and should also be able to hide notes. Thanks to my app BlueJamPlayer, I already had the basis for the audio player, song analysis and control via foot pedal. I also took over the effect section, so that you can use the 7 audio effects in the BlueScalesTrainer as well. Here are the extensive functions that I have integrated in the BlueScalesTrainer and everything without subscription, InApp Purchase or advertising: - The main Scales are included: Major, Minor, Pentatonic Major, Pentatonic Minor, Blues Major and Blues Minor - In total 360 scales for your training target to master your guitar solos - Per scale type each of the 12 keys and their 5 patterns according to the CAGED system could be selected - Scale view in 3 modes: Pattern single, Summary and Zoom view - New added large fretboard view, where either root notes, chord notes or all notes of the scale are displayed - Switchable display of the notes or note position in the scale - The player can also be controlled via Bluetooth from PagerTurner foot pedals - Alternative scale views can be switched via foot pedal - The pitch can be adjusted without changing the speed - Also the speed is adjustable without changing the pitch - Free configurable effects (reverb, delay, flanger, equalizer, filter) to improve the sound - All songs in your iTunes library can be used - Songs are analyzed for the key, so that the matching scale will be selected automatically - The BPM will also be analyzed and effects Delay/Flanger will be set to this BPM - In order to sort your session better, there is a playlist management with 16 playlists - Especially for practicing difficult passages, the A->B Play mode is optimal - For the direct start 14 loop songs of different styles already available Hope you enjoy learning Scales with BlueScalesTrainer!
