Intonation is really a vital step for making the instrument sound its best. Tuning is only a part of it and as your strings are each tuned to the right pitch, what happens is that the chord at a whole does not sound right. If you notice this on your instrument, then it is time to intonate. What you will need in the first place will be a tuner (connected to the instrument if possible). A standard chromatic tuner will do and you will also have to have something to adjust the bridge with (for my squier strat a simple small screwdriver will do). You can start with any string you like and the first step is playing a harmonic note on the 12th fret. Measuring with the tuner will tell us if any work has to be done at the tuners. You should check thet the actual pressed-down note and the narmonic sound on the same pitch. While testing make sure to use the screwdriver adjust the saddles (slowly and test a lot) to the position where the string sounds the same played normally and as a harmonic, both of which should be an octave up from the open note. After you have finished all the strings check and fix as many chords as you like and you are done.
While you may or may have not stringed an instrument till this point, this is a technical step by step list for stringing. Firstly, stretch the strings so that they do not stretch themselves while you are playing (will go out of tune fast and a lot of times until it stretches itself properly) Secondly you have to get the string through the tuning pegs. What I would recommend if you are going for a full restringing is that you start from the thinnest to the thickest (if you have a Fender Stratocaster-like neck) and from the thickest to the thinnest for the acoustics. The main idea is that you start from the top of the headstock, so as to make sure that the strings that you have put on at a certain point do not bug you afterwards (this may differ for leftty instruments). After you have done this, aim the end of the string in the direction of the headstock, so as to not get stinged by it, and bend. Then fold the end of the string over the rest, making sure to have something resembling a knot. Then, slowly start turning the peg and make sure to use a tuner when the tension adds up. After getting it in tune, you can cut the excess string.
The Hip-Hop Drum Pads 24 app is a free Android app for making hip-hop music. It has a 3x4 grid for all the pads and a lot of other functions. You can pitch bend the sound, hold (sustain) the pad and also record with the external microphone. There are 10 hip-hop presets for this app and they all are free. You can see your recordings listed in the side panel of the app, as well as look out for tutorials and other apps. There are categories for the presets, where you can see all the presets, downloaded presets and your favorite that can be set. The app is made very well, runs smoothly and does not crash and it is almost as good on a phone as it is on a tablet. You will have to use a new Android version to run it and a good processor can only help. This app requires only microphone permission and works just well. The Hip-Hop Drum Pads 24 is a really up-to-date app that can deliver great songs, but would be better off used with an amplifier and a separate microphone, so that you do not get all that much touchscreen sound.
The Harmony app is a free circle of fifths app for Android phones and tablets. It first displays a menu with the circle of fifths with a selector. You can use the classical circle of fifths or the open key version. There also is a classical open key setting, but it only changes the G# into A b and the D# into E b. The main distinctive feature of this app is that it has a configurable setting you can use to make your own circle of fifths. The user interface is great and the app is easy to use. The version of the circle you can modify is the open key classical circle, but there is a problem here. You can write anything here, as there is no processing going on about that. Apart from that the app also has a power off button that quits the app even if it leaves it processing, it does not close it totally. The app is great if you have the time to configure you custom setting all by yourself, but even if you do not, you can make use of the standard pre-settings for the classical circle of fifths.
The Guess the note app is a really good app for people that want to learn to recognise notes. You can use it both in order to run through notes and practice, as well as test yourself on two levels of difficulty. The first level containg only natural notes and the other contains all the notes. There is also a score that is being kept track of, including highscores. The notes are recorded really well and you can really train with this app. Even if not all sounds are included in this app, the included sounds are good practice for beginners and intermeriates . There is a tick tack option to the game and a lot of settings. Well, not really but you can select the note notation. Going back, the tick tack game is a cronometered version of the game that lasts as long as you are able to guess the note, based on a score that it also displays. The app is not complicated to use and even if it is not professional, it looks and works all right. The guess the note app is great all screens of all sizes.
The G-Stomper app is probabily the most complex drum seqvencer in all Android apps. It has 12 preinstalled acoustic drum sounds, but you can add as many as you want, as well as a lot of settings to make your loop. You have sliders for shuffle, normal and reverse, fill in, pan, level, start length, speed, pitch, amplifier, ram and a play menu. This app also has a mixer, equiliser, a whole menu for tempo, recording capabilities, a 16 piece step sequencer and a general menu with output methods and more. You can load patterns, sound sets and samples. You can save patterns, clear them, make output files either MIDI or audio, share what you have created or get help with the app. In the save menu you can select the number of times you want the cycles to be in your audio file, where to place it and a lot of settings. It delivers .wav files, which can contain all or just a part of the tracks. The G-Stomper is a really functional app that does a lot even in the free demo. It can be used by beginners and advanced professionals as it is made to furfill all needs and is best used on a tablet screen.
The Granular app is a free Android app for making granulator music. The app can use either user sounds or presets and from that point on you can set pitch variation, grain interval and randomness. After doing that you can share what you have created or delete if you do not like how it sounds like. In order to granulate your own files, you can place .wav files in the /mnt/sdcard/Granular folder. The sounds that this app produces are amazing, mostly because of its small size. The app is usable on both phones and tablets but it does require at least Android 4.2. The Randomness function is not random at all, and produces really good patterns as far as granulation can go. You can use this app as a sampler, as it is capable of producing really complex sounds. The app is best used with a new processor, so that it does not lag or crash. The Granular app is a really functional app for making electronic music or to at least edit music that you have already composed and wish to add a slight retro effect to.
The Grainstorm app with so many options I could right about, but the first things are first, the Grainstorm app is a sound manifulation app. It has 4 channels you can record on and on each you can change the sound on. After you have recorded a sound you enter the first menu. This first menu enables you to set the grain, speed and pitch of the sample. Then you move to a granulation menu with effects, then the inner and outer envelope. There are depth and cycles effects and on the next page there is a control and envelope selector as well as frequency and depth control. The next menu is a modulation menu, then we have a phase vocoder and winsize selectors and the final menu is a modulator. There are other sub-menus you can use and also an accelerator and deccelerator. You can double the speed or set it to half, as well as cutting a measure off. You can also mute channels and play only what you want at a time. This app is great for working with sound while not in front of a computer screen, even if the controls are hard to use and loading files comes only in the paid version.
The Geo Composer app is a free Android app for making music. You have two main instruments: a synth with a single sound and the piano. Then there is a percussion generator and everything looks like a piano chart/drum sequencer. There are many subdivisions to the timeline and they would only fit on a 10" tablet. The app does not play in background, but it can play over other songs. The 16x16 timeline can be set to play in most key: A, A#, B, B#, C, C#, D, D#, E, E#, F, F#, G, G# and in most scales: major, minor, pure minor, dorian, flamenco, mixolydian, lydian and harmonic minor. You can have four tones for each instrument, a volume slider, reverb level and decay, delay level and decay and you can set the time signature: 1/4, 1/4., 1/8, 1/8., 1/8T, 1/16 and 1/16. . You can pause or play the sequence, and you can have 8 sequences per each instrument. You can save as much 18 compositions, and load them as well as make a new start-up file. This app is any goon only on a large screen tablet.
The EQ Bass app is a free Android app for setting the volumes of each of the provided frequencies. The app is an exact copy of the Bass Booster 2017 but has a different skin. The major thing that you can observe and see to be different from the other app, is that it has a music visualizer. It also has: a transparent background, which is useful if you want to see which song you are adjusting, as well as to see the time and notifications provided by your phone or by your tablet. The rest of the functions from the background do not really work. What is most likely is that the app captures a picture of your screen before you actually use the app and sets it as a background for itself. The app can be switched on and off from the notifications menu, which you would be able to access if you have Android 6.0 or up. The EQ Bass is a free Android app which you can use to vary songs of your own and see how they sound, as well as use the app to adjust other people's songs to go good with your headphones.
